Gebühren: Wie viel kostet Bitcoin Loophole?

Published Post author

Es gibt in der Regel vier Arten von Gebühren, auf die Sie bei der Auswahl einer Handelsplattform achten sollten. Auf diese sollten Sie achten, wenn Sie eine Anlage- oder Handelsdienstleistung bewerten:

Nicht-Handels-/Sonstige Gebühren

Jede Art von Gebühr für den Handel auf dieser Plattform, die oben nicht aufgeführt ist. Ein Broker könnte Ihnen beispielsweise Gebühren für Einzahlungen auf Ihr Brokerage-Konto, für Abhebungen oder für die Inanspruchnahme zusätzlicher Dienstleistungen in Rechnung stellen.
Bitcoin Loophole ist weder eines der billigsten noch eines der teuersten Produkte auf dem Markt. Wie bei professionellen Produkten üblich, erhebt es nicht den Anspruch, völlig kostenlos zu sein. Allerdings ist es billiger als viele vergleichbare Dienste.

Diese Plattform basiert auf einer Preisstruktur, die stark an die individuelle Nutzung gebunden ist. Es gibt gestaffelte und feste Preispläne, und in einigen Fällen wird der Handel ohne Provisionen angeboten. Bei den Festpreisplänen wird der Preis pro Vermögenswert oder pro Handel im Voraus festgelegt, unabhängig von Ihrem Handelsvolumen oder Kontostand. Ein gestaffelter Preisplan bewirkt das Gegenteil, indem er Ihre Preise pro Vermögenswert oder pro Handel auf der Grundlage Ihres Handelsvolumens in einem bestimmten Monat skaliert. Bei diesen Plänen hängen die Preise auch davon ab, wo Sie wohnen und auf welchen Märkten Sie handeln.

Der Handel zum Nulltarif ist für bestimmte Konten und für bestimmte Vermögenswerte möglich.

Ein US-Anleger, der auf den US-Märkten handelt, könnte beispielsweise einen Festpreisplan für den Aktienhandel wählen. In diesem Fall würden sie 0,005 $ pro gehandelter Aktie zahlen, mit einem Mindestpreis von 1 $ pro Auftrag und einem Höchstpreis von 1 % des Gesamtwerts der Transaktion. Ein gestaffelter Preisplan für denselben Anleger würde sich danach richten, wie viele Aktien pro Monat gehandelt werden, beginnend bei 0,0035 $ pro Aktie, wenn weniger als 300.000 Aktien pro Monat gehandelt werden, bis hinunter zu 0,0005 $ pro Aktie, wenn mehr als 100 Millionen Aktien pro Monat gehandelt werden.

Diese Preisstruktur gilt für alle von Bitcoin Loophole unterstützten Anlageklassen, wobei es für jede Anlage, jeden Plan und jeden Standort unterschiedliche spezifische Preispunkte gibt.

Schließlich bietet Bitcoin Loophole Lite einen provisionsfreien Handel. Damit versucht die Plattform, Kleinanleger anzusprechen. Mit Bitcoin Loophole Lite können Sie mit Aktien und börsengehandelten Fonds (ETF) zum Nulltarif handeln, haben aber keinen Zugang zur Trader Workstation der Plattform. Anleger mit dem Lite-Plan nutzen die web- und app-basierten Handelsportale der Plattform. Sie können mit der gesamten Palette an Vermögenswerten der Plattform handeln, aber nur Aktien und ETFs sind kostenlos. Lite-Abonnenten müssen nach wie vor für andere Vermögenswerte auf der Grundlage eines gestaffelten oder festen Preismodells zahlen.

Handelsgebühren

Jede feste Gebühr, die für jeden von Ihnen getätigten Handel anfällt. Dies kann in Form einer Pauschalgebühr oder eines so genannten “Spreads” geschehen. In diesem Fall berechnet Ihnen Ihr Broker die Differenz zwischen dem Kauf- und dem Verkaufskurs eines Vermögenswerts, sofern vorhanden.

Handelsprovisionen

In diesem Fall berechnet Ihnen der Broker einen Prozentsatz auf der Grundlage des Volumens oder des Wertes eines jeden Handels.
Inaktivitätsgebühren – Alle Gebühren, die der Makler Ihnen in Rechnung stellt, wenn Sie nicht handeln, z. B. wenn Sie Geld auf einem Maklerkonto halten.

Bitcoins markedsverdi vil overstige Teslas innen seks måneder, sier Galaxy Digital CEO

Published Post author

Galaxy Digital-sjef Mike Novogratz sier at Bitcoins markedsverdi vil formørke Teslas innen juni 2021.

Lederen for firmaet for digital kapitalforvaltning tok til Twitter for å forklare hvorfor han mener Bitcoins markedsverdi vil vokse mye raskere enn Teslas i løpet av de kommende månedene.

BTC vil ha større markedsverdi enn TSLA innen 6 måneder

Begge er ‘religioner’, selv om TSLA har så stor risiko rundt Elon Musk mens BTC eies og drives av et gigantisk desentralisert samfunn som vokser hver dag. Det er et risikostyringsspill. Full avsløring Jeg eier to TSLAer. ”

I skrivende stund er Bitcoins markedsverdi over 428 milliarder dollar, mens Teslas ligger på 616 milliarder dollar.

I et nylig intervju med Real Vision sier Novogratz at både Bitcoin og Tesla er en del av et omfattende oksemarked drevet av lave priser og økende vekst

«Jeg snakket med en av – jeg vil ikke nevne navn, men en av de bokstavelig talt de fem største legender i investeringsverdenen i morges. Jeg sa, jeg er bekymret for at Airbnb økte 120% på første dag, Snowflake med 100 ganger inntekt, og jeg snakket med en annen venn, og han gikk fra å være verdt $ 2 milliarder til $ 8 milliarder… og det bekymrer meg virkelig.

Jeg forstår at vi kommer til å holde rentene lave for alltid, og veksten tar seg opp. Jeg elsker rå, jeg er lang rå. Du kan være lang kobber. Vi kommer til å ha en stor vekstoverraskelse tidlig neste år, og i andre kvartal vil den eksplodere. Det er en makro grunn til å være lang. Hans syn var han sa, hør, det er skummelt. Det gir ingen mening. Du må bestemme deg, skal jeg ri på den eller ikke?

Så angrer du ikke hvis du bestemmer deg for at du ikke skal ri på den, som om vi kjører på denne vanvittige boblen av dette nye regimet som vi er i når du skriver ut mer penger enn vi noen gang har sett før. Hva som driver Bitcoin, driver Tesla og Snowflake og alle satsinger tilbake. ”

Lo siento, Bitcoin y Altcoins empiezan a ser el centro de atención de los medios de comunicación.

Published Post author

Los precios de Bitcoin (BTC) han estado acaparando todos los titulares de los medios de comunicación últimamente, con la señal empujando hacia la clave de 20.000 dólares.

pero con los altcoins también surgiendo, algunos grandes medios de comunicación convencionales están ayudando a millones de sus lectores a encontrar altcoins que superaron al BTC.

En un informe de aproximadamente 1.000 palabras llamado “Más allá de Bitcoin: estas criptodivisas están mejorando aún más”, Bloomberg se sumergió profundamente en el mundo de las monedas alternativas, comentando que fichas como el etéreo (ETH), XRP de Ripple, litecoin (LTC) están actualmente “dando a la moneda digital más famosa del mundo una carrera por su dinero”.

El periodista Edward Robinson escribió que algunas “criptodivisas están publicando números aún más llamativos que el progenitor del dinero digital”.

Señaló a ETH como nota, llamándola “la favorita desde hace mucho tiempo de los geeks de la tecnología”, con XRP etiquetado como “un pararrayos para los criptocríticos”.

Sin embargo, el medio advirtió que los “veteranos del cripto” afirmaban que apresurarse a comprar monedas alternativas equivalía a “hacer apuestas basadas en poco más que el impulso del mercado”, lo que podría ser una decisión “imprudente”.

Robinson escribió,

“Mientras que muchas de estas criptodivisas se elevaron junto a bitcoin en 2017, también lo hicieron en picado cuando bitcoin se derrumbó en 2018 y se empantanó en un período conocido como criptoinvierno. Ahora parecen estar siguiendo el mismo patrón una vez más”.

Y Robinson incluyó una “guía de las alternativas más valiosas a Bitcoin en el universo criptográfico”, nombrando de nuevo a ETH y XRP, así como a LTC y añadiendo,

“Una nueva generación de activos digitales que sube en la tabla de clasificación está más influenciada por el diseño de Ethereum que por el de Bitcoin. Tres de los más destacados son chainlink (LINK), cardano (ADA) y polkadot (DOT)”.

Últimamente, Altcoins también ha estado en la cima de Google Trends, lo que sugiere que puede que no sean sólo los periodistas de la corriente principal los que han desarrollado un interés en ETH, XRP y el resto de los últimos tiempos.

Mientras tanto, la CNN siguió una táctica muy similar en un artículo llamado “Olvídese de Bitcoin”. Estas criptodivisas están surgiendo aún más”.
El escritor de negocios de CNN Paul R. La Monica escribió sobre XRP, también, también sobre el nombre de litecoin, polkadot, cardano y stellar (XLM).

La Monica explicó,

“Estas monedas más pequeñas están hasta cierto punto montando el bombo que ha llevado a Bitcoin a un nuevo récord. Bitcoin se ha beneficiado de un dólar más débil y de las expectativas de que un período prolongado de tasas de interés súper bajas creará eventualmente una inflación. Eso aumenta el atractivo de una moneda digital”.

Y en un florecimiento alcista que llenará de alegría a las animadoras de Altcoin, añadió,

“Muchas criptocurrencias han funcionado bien últimamente, varias de ellas todavía están muy por debajo de sus picos – a diferencia de bitcoin. Así que pueden tener más espacio para ponerse al día.”

Mientras tanto, a principios de este año, la principal criptoteca Coinbase dijo que aunque la mayoría de sus usuarios inicialmente favorecen el BTC, la gran mayoría también pasa a comerciar con monedas alternativas y otros activos digitales: “Entre los clientes con al menos cinco compras, el 60% comienza con bitcoin pero sólo el 24% se adhiere exclusivamente a BTC.”

En el momento de escribir este artículo (08:58 UTC), BTC cotiza a 19.402 dólares y no ha cambiado en un día, subiendo un 15% en una semana. El precio ha subido un 42% en un mes y un 165% en un año.

Value DeFi loses $ 6 million in “flash loan exploit”

Published Post author

Value DeFi is the next DeFi project to fall victim to a serious attack.

The DeFi project Value DeFi fell victim to a so-called “flash loan exploit” , which caused damage of almost 6 million US dollars

The attacker in question used two “flash loans” from other DeFi projects in order to use them to use the exchange rate differences at Value DeFi to their own advantage. So he just found a “gap in the system” and cannibalized it or “exploited” it.

Explanation: Flash loans are crypto loans that are approved without the borrower having to deposit a corresponding deposit. This is possible because the respective loans are literally repaid “in a flash”, because they still have to be paid within the same blockchain transaction.

At 10:45 a.m. (EST) a crypto user had such a flash loan of 80,000 ETH (more than 36 million US dollars) from the Aave project paid out on Friday. Aave developer Emilio Frangella noticed this unusual occurrence and accordingly pointed it out on Twitter:

Emiliano Bonassi, a self-proclaimed Whitehat hacker and co-founder of DeFi Italy, then reported that the attacker had withdrawn a flash loan in the form of the stablecoin DAI from the DeFi project Uniswap, which in turn corresponded to the equivalent of 116 million US dollars .

As Bonassi further noted, the attacker exchanged the ETH borrowed from Aave for stablecoin funds, then deposited part of the DAI received from Uniswap into Value DeFi’s multi-stablecoin vault, and then made several exchanges between the stablecoins USDT, USDC and DAI carried out in order to “exploit” the differences in the exchange rate within Value DeFi.

In an interview with Cointelegraph, Bonassi explains that the attack was conceptually similar to the most recent attack on the DeFi project Harvest Finance , but that the action against Value DeFi is the most complex exploit he has seen so far. In addition, it would have been “the first time” that an attacker used two flash loans at the same time.

A little later, Value DeFi admitted the attack in the company’s own Discord server:

“We are aware of the current processes in the MultiStables Vault. Please give us time so that we can examine it carefully. All other vaults and pools run normally. ”

Shortly after the exploit was over, the attacker sent an Ethereum transaction to the Value DeFi address , which he used to mock the project’s operators. So he asked sarcastically:

“Do you already know what flash loans are?”
The attacker only paid $ 0.31 in ETH with his transaction, which is further evidence that the news was all about scorn and ridicule.

New day, new hack: Scammers steal $ 2 million from Ethereum DeFi app

Published Post author

With the billions of dollars floating around, it’s no surprise that hacks and software bugs keep popping up in the decentralized finance (DeFi) space.

To name one of the many recent weaknesses of DeFi contracts: Harvest Finance was hacked into stablecoins for 25-33 million dollars – due to a so-called “flash loan attack”.

There was a flaw in the economic logic that the developers at Harvest ignored and that allowed a tech-savvy attacker to withdraw funds.

Similar attack vectors have been exploited with contracts like that of Eminence Finance, an Ethereum- based game that users have invested millions in even though there was no official launch announcement.

The hack transactions on Etherscan

Not to mention, there are a number of fatal mistakes. For example, the developers at Yearn.finance (YFI) had to fix a bug that would have allowed a user to steal $ 650,000 worth of stablecoins from one of their products.

The error was similar to the one used to withdraw funds from Harvest. Unfortunately, not all bugs are discovered and eliminated before they are exploited.

MakerDAO’s Stablecoins worth around $ 2 million were recently stolen from the Akropolis app. Akropolis is a full-fledged DeFi protocol that focuses on giving “normal people” the opportunity to save their stablecoins and earn interest. Your savings product has now been exploited by an unknown attacker.

Acropolis Ethereum DeFi application hacked for $ 2 million

Early Thursday, Ethereum analysts and Acropolis users began to notice suspicious transactions in the Acropolis savings product called Delphi.

It quickly became clear that an attack had taken place. Data from the chain indicated that the DAI had been routed from Acropolis to an address that was interacting with the log dozens of times per minute – suggesting something was going on.

Within twenty minutes, the attacker sent dozens of transactions to a number of Acropolis Delphi savings pools, each time subtracting a sum of the DAI from the pool.

A total of 2,030,000 DAI were apparently illegally withdrawn from the Acropolis.

These stablecoins were sent to an address and have been there ever since. The alleged attacker has not yet sent a transaction from the address where the stolen funds are located.

How did that happen?

Crypto asset auditing and security firm PeckShield, which has been focusing on DeFi for the past few months, has broken down the details of the attack hours after it was carried out.

To keep it simple, the attacker used a lightning loan from dYdX to trick Akropolis’ smart contracts into thinking they had deposited funds that the attacker really didn’t have. While some funds were being deposited, the attacker was provided with liquidity tokens worth more than the amount deposited, creating a discrepancy that could result in large withdrawals from the pool.

“The exploit resulted in a large number of pool tokens that were minted without being backed by valuable assets. The withdrawal of these coined pool tokens will then be exercised in order to deduct around 2.0 million DAI from the YCurve and sUSD pools concerned, ”said Peckshield.

Akropolis has also responded to the attack, writing that they are reviewing the code and looking for ways to compensate the affected users of the protocol.

Bitcoin Whale: US government seizes USD 1,000,000,000 in BTC from SilkRoad

Published Post author

A few days ago, a very large bitcoin whale alarm was making the rounds. Almost 70,000 BTC, the equivalent of just over 1 billion US dollars, were moved out of the fourth largest Bitcoin wallet . This was the first transaction since April 2015. Now it was revealed who is actually behind the transaction and what the background is.

Bitcoin Whale: U.S. Justice Department

Last Thursday, the world-famous Bloomberg portal reported the seizure of a gigantic amount of Bitcoin by the US Department of Justice. Accordingly, the enormous sum of 1,000,000,000 USD was confiscated, which came from the activities of the now closed darknet market called Silk Road.

The US Department of Justice said:

The amount seized is by far the largest sum of cryptocurrencies that has ever been seized in the history of the ministry.

According to the investigators, there was a collaboration with the company Chainalysis, known in the cryptospace. The aim of the collaboration was to identify Bitcoin transactions that were directly related to Silk Road. Obviously, this cooperation was successful and 54 transactions were discovered that were generated by an illegal activity.

0.33% of all available BTC in the hands of the Ministry

The Ministry of Justice said:

The flow of money was traced back to a Bitcoin address. Further investigation of this address by the US Attorney’s Office and other investigators revealed that the funds were related to Silk Road. Subsequently, on November 3, 2020, law enforcement authorities seized several thousand Bitcoin, which on November 4 had an equivalent value of over 1 billion dollars.

In addition to this enormous amount of Bitcoin, holdings of Bitcoin Cash, Bitcoin Gold and Bitcoin SV were also confiscated. And so the US Attorney David Anderson ended the statements with:

The successful arrest of the Silk Road founder in 2015 left the question of where the money was going. Well we have the answer. $ 1 billion of criminal activity is now in the hands of the United States.

This solves the mystery of the mighty Bitcoin Whale. It is also interesting that the US government is increasingly becoming a BTC whale. With almost 70,000 BTC now seized, the US Department of Justice alone holds 0.33% of the available supply of Bitcoin.

How the increase in US GDP will influence Bitcoin

Published Post author

Tax risk and fall in interest rates may serve as incentives for investment in Bitcoin

The US GDP grew 33.1% in the third quarter, even in an atypical Pandemic year. In the quarter by quarter comparison, this means a growth of 7.4%. An excellent news for Donald Trump who will dispute the election next Tuesday, November 3. Considering the collapse in the second quarter, this means that the level of real GDP is still 4.5% below its peak.

With the increase of the GDP in the USA and the consequent devaluation of the dollar against Bitcoin Bonanza, an average investment opportunity will arise for investors who will seek in Bitcoin greater profitability and refuge from fiscal and inflationary risk. This premise will be valid both for the USA and for Brazil.

Taking into account current GDP estimates, the US GDP will probably reach a new peak in the last quarter of next year, closing a cycle of monetary expansion and public spending, which at some point will be charged to the stimulus account of more than $1 trillion released last quarter and another $5 trillion being released by the Federal Reserve (Fed) to keep the economy warm. By the numbers presented in the GDP, the stimulus worked.

With everything that happened as a result of Covid-19, one can say that the result of the US GDP is quite impressive and is in line with the result presented by China, which was in the order of 4.9%. This shows that the close cooperation of fiscal and monetary stimulus has been effective, probably avoiding an environment similar to the depression followed by the 2008 crisis.

Japan is ‘main candidate’ for new Ripple headquarters, says SBI Holdings CEO

The latest data also increases Trump’s chances of being re-elected, although he is way behind in betting odds and research. But it was the same in 2016. What’s also surprising is that if you give people money, they will spend it – even with unemployment reaching historic levels, both in the US and Brazil, which already represents 13.3% of unemployed people, according to data released by Ipea.

The solution to the social networks dilemma

Personal consumption grew more than 40% (annualized) in the third quarter. This is a very impressive multiplying effect. So, although we are not out of danger yet – we need a vaccine to get there – things don’t look so bad compared to six months ago. Even the most fragile economies, like Brazil’s, but which was warmer before the Pandemic, the results of the Brazilian GDP in the last quarter, of the order of 5.8%, a better result than expected by the IMF, which was of the order of 9.1%.

A global crisis, but with local results

The Pandemic crisis affected all countries and their economies, each responding to the challenge according to the instruments that their governments and companies had available. The fact that stock exchanges and stock markets show expressive numbers of appreciation ignores the real numbers of the microeconomy, which concern the small neighborhood cafeteria, which closed, while in the macroeconomic aspect, the numbers presented by Starbucks are of growth in the same period. The shares of the coffee chain, valued at US$ 116 billion, have increased 50% so far this year.

WhatsApp Pay should reach Brazil in November, according to Cielo

Increase in US GDP represents an opportunity for Bitcoin

Both countries continue with increasing fiscal risk and low interest rates, creating an environment in which the search for assets with more risks, such as the stock market, or the cryptoactive market, become preferential options for those seeking more profitability.

BitMEX executives have allegedly “looted” $ 440M from the platform to avoid their seizure

Published Post author

Already involved in important legal actions carried out by American institutions, the co-founders of BitMEX are again accused of fraud. A civil action accuses them of having “looted” more than $ 440 million from the platform in order to reduce the funds that can be seized by the authorities.

New episode of the BitMEX affair

A civil lawsuit filed on October 30 alleges that BitQT executives have ” looted ” more than $ 440 million from the platform . Manipulation of funds that would have started in 2019, while government investigations were already underway on the company’s activities.

The lawsuit was brought by traders Vitaly Dubinin and Yaroslav Kolchin against the co-founders of BitMEX’s parent company, HDR Global Trading Limited . The charges are notably brought against Arthur Hayes , Benjamin Delo and Samuel Reed .

“The defendants Hayes, Delo and Reed are notorious fraudsters, who have been charged with criminal offenses related to money laundering by the US Department of Justice and two of them are currently fugitives from law enforcement American, ”underlines the complaint.

SOSventures , a venture capital firm founded by entrepreneur Sean O’Sullivan and having invested in BitMEX , is also believed to be involved.

The lawsuit argues that BitMEX executives engaged in this practice to reduce the amount of assets likely to be seized by the relevant authorities. The table below shows the alleged distribution of funds looted by the co-founders of BitMEX .

A spokesperson for HDR Global Trading denied these claims, telling Coindesk :

“Pavel Pogodin of Consensus Law has filed a series of increasingly bogus complaints against us and others in the cryptocurrency industry. We will deal with this matter through normal legal process and have every confidence that the courts will consider his claims for what they are. ”

Exchanges in the sights of regulators

The accusations against BitMEX and its co-founders are accompanied by other actions on a larger scale.

The platform’s descent into hell began in early October, when the Commodity Futures Trading Commission (CFTC), a regulator of U.S. markets, accused BitMEX owners of violating anti-money laundering regulations. .

As a result, a large part of BitMEX users fled the platform, drastically reducing the liquidity of its markets. Less than a week later, Arthus Hayes, CEO of BitMEX, leaving office .

Recently, all eyes have been on Binance , the world’s largest cryptocurrency exchange. The company would have sought to circumvent US regulations, according to a leak of documents shedding light on the existence of an entity called ” Tai Chi “, which made it possible to channel profits to Binance.

These serious accusations were quickly denied by Changpeng Zhao , CEO of the platform. He claimed on Twitter that the said document was not produced by a Binance employee and that anyone can originate such a document.

Either way, regulators and watchdogs around the world are taking an increasingly serious look at the activities of cryptocurrency exchanges. With the billions of dollars flowing through them daily, it’s not all that surprising that their activities are subject to audits.

La comunità Crypto risponde al governatore della BoE sul valore intrinseco della Bitcoin

Published Post author

Il valore intrinseco del bitcoin è stato ampiamente discusso nello spazio criptato per diversi giorni dopo che un’osservazione del governatore della Banca d’Inghilterra (BoE) ha suggerito che l’ammiraglia cripto potrebbe non avere alcun valore intrinseco.

Del bitcoin in una sessione di domande e risposte

Andrew Bailey, governatore della BoE, ha commentato il valore intrinseco del bitcoin in una sessione di domande e risposte con il pubblico all’inizio di questa settimana. Egli è stato citato da Reuters come dicendo:

“Devo essere onesto, è difficile vedere che il bitcoin ha quello che noi tendiamo a chiamare valore intrinseco. Può avere un valore estrinseco nel senso che la gente lo vuole”.

Ha anche detto che le persone che usano il Bitcoin Revolution per i pagamenti lo rendono piuttosto nervoso, dato che il valore della crittovaluta è ancora incerto. Dopo queste osservazioni di Bailey, la comunità dei crittografi ha iniziato a discutere in dettaglio del valore intrinseco del bitcoin.

Anche l’amministratore delegato della società quotata al Nasdaq Microstrategy, Michael Saylor, ha avuto voce in capitolo. Microstrategy ha recentemente acquistato bitcoin per un valore di 425 milioni di dollari per la sua riserva di tesoreria. Saylor ha twittato:

“Bitcoin è il primo sistema monetario digitale in grado di immagazzinare tutto il denaro del mondo per ogni individuo, società e governo in modo giusto ed equo, senza perderne nulla. Se questo non ha un valore intrinseco, cosa lo è?”

Nikolaos Panigirtzoglou, strateghi di JPMorgan, ha scritto in una nota del 13 ottobre sul valore intrinseco di bitcoin che si avvicina al suo prezzo di mercato.

“Il Bitcoin si trova ad affrontare un “modesto vento contrario” a breve termine, basato su un’analisi delle scommesse nel mercato dei futures e su una stima del valore intrinseco della criptovaluta”.

Bloomberg ha riportato gli strateghi spiegando e aggiungendo che il prezzo rimane quasi il 13% in più di una stima del valore intrinseco.

Twitter Crypto Community Awakened

Diverse persone su Twitter sono state rapide nel sottolineare che il bitcoin potrebbe non avere un valore intrinseco definito. Ma anche le monete fiat non hanno un valore intrinseco. La Federal Reserve Bank of St. Louis ha scritto un rapporto nel 2018 dicendo:

“Il bitcoin non è l’unica valuta che non ha valore intrinseco. Anche le valute monopolio di Stato, come il dollaro americano, l’euro e il franco svizzero, non hanno valore intrinseco. Sono monete fiat create per decreto del governo. La storia delle valute di monopolio statale è una storia di oscillazioni selvagge dei prezzi e di fallimenti. Per questo motivo le crittocittà decentralizzate sono una gradita aggiunta al sistema valutario esistente”.

L’amministratore delegato di Shapeshift Erik Voorhees ha detto che non esiste un valore intrinseco. Egli ha spiegato:

“Il valore è sempre soggettivo, agli occhi del valutatore … Oro, bitcoin, fiat, riso: nessuno ha ‘valore intrinseco'”.

Anche un altro utente di Twitter, Bob McElrath, concorda sul fatto che nulla ha valore intrinseco, poiché il nome ‘valore’ è il sentimento umano. Il valore cambia di volta in volta e con le circostanze. Chiunque cerchi di convincerti del contrario nella maggior parte dei casi vuole vendere qualcosa a te per il proprio guadagno. McElrath ha aggiunto:

“Nonostante non abbia un valore ‘intrinseco’, il bitcoin ha un modo sofisticato, basato sul mercato, per determinare il suo valore, non solo sul lato della domanda ma anche su quello dell’offerta. Naturalmente, questa affermazione vale per qualsiasi merce”.

Ha optato George Selgin, direttore del Centro per le Alternative monetarie e finanziarie di Cato:

“Naturalmente nessuna merce ha un valore “intrinseco”. Alcuni (come qualsiasi moneta fiat) mancano anche di ‘valore d’uso non monetario’ … l’osservazione della Banca d’Inghilterra che il bitcoin manca di valore intrinseco è un esempio del bue che chiama il bue che dice cornuto all’asino”.

Questo dibattito può continuare all’infinito, ma questo non dissuade gli investitori interessati dal tuffarsi nello spazio del bitcoin. Sempre più investitori istituzionali stanno entrando nel mercato, cosa che molti sostenitori ritengono essere un segno positivo per il futuro del bitcoin e dei cripto in generale.

Bitcoins Lyn-nettverk har oppdaget andre sikkerhetsproblemer

Published Post author

Conner Fromknecht, en utvikler av Lightning, har nylig publisert en avsløring 9. oktober 2020 til adresselistene til prosjektet. Denne avsløringen råder forskjellige nodeoperatører så snart som mulig, da Lightning-utviklerne hadde oppdaget et sårbarhet i nodeprogramvaren til Bitcoin Lightning Network.

Fullstendig informasjon offentliggjort 20. oktober 2020

Slik det ser ut nå, er alvoret i dette sårbarheten uklart, da avsløringen avstår fra å avsløre nøyaktig hvordan denne sårbarheten blir utnyttet. Rapporten antyder imidlertid at utnyttelsen ennå ikke skal brukes i naturen. Tilfeldigvis er mange Lightning node-operatører allerede trygge for det, ettersom feilen allerede var løst fra versjon 0.11 av Lightning Network-programvaren, som ble utgitt i slutten av august.

Likevel var sårbarheten som ble oppdaget av en slik type at avsløringsprosessen måtte forkortes for å beskytte nettverket generelt. Ifølge innlegget vil en fullstendig avsløring av feilen bli utgitt 20. oktober 2020, med håp om at alle nodeoperatører hadde oppdatert programvaren sin da.

Bug Bounties å holde seg trygg

I tillegg til dette hadde Lightning Labs gjort det klart at de planlegger å lansere et nytt, omfattende bug bounty-program i nær fremtid. Dette programmet vil gjøre det mulig for potensielle sikkerhetsspesialister å kreve en belønning hvis de oppdager feil i fremtiden, noe som vil hjelpe Lightning til å holde seg trygg.

Lightning Network står som en Layer 2 betalingsprotokoll som fungerer på toppen av Bitcoin. Mens det fremdeles er under utvikling, tillater det billigere, raskere transaksjoner innen nettverket generelt.

Mindre hikke, men grunnleggende lyd

Dette står som det andre registrerte sårbarheten som ble oppdaget i nodeprogramvaren til Lightning. Bare i fjor hadde Rusty Russel, en Bitcoin-utvikler, funnet en egen sårbarhet som gjorde det mulig for angripere å stjele brukernes midler gjennom bruk av å sende ugyldige transaksjoner. Lightning Labs hadde valgt å ikke avsløre antall brukere som ble offer for dette, men bekreftet at utnyttelsen ble brukt i naturen.

I begge tilfeller av disse utnyttelsene kom det som et resultat av programmeringsovervåkning som var veldig kortvarig. Som sådan har det ennå ikke vært en grunnleggende designfeil i selve lynet, som alltid er bra. Lightning Network er en av de mest lovende måtene å øke hastigheten på transaksjonene i Bitcoin-nettverket, samtidig som transaksjonsavgiftene reduseres.

CoinGate og Bitfinex, viktige aktører innen kryptoindustrien, har allerede adoptert Lightning Network uten noen tilsynelatende problemer fra deres side. Nettverket ser generelt ut til å være fundamentalt robust, med bare noen få kinks på utsiden.
