Technische Probleme und die passende Hilfe

Cet article fournit une mise à jour (à partir de 08:00 UTC le 17 février 2021) sur l’état actuel des marchés de Bitcoin, ainsi que sur les dernières réflexions sur Bitcoin par des analystes cryptographiques, des investisseurs, des traders et d’autres leaders d’opinion influents.

Ce qui a permis à Bitcoin de franchir la barre des 50 000 dollars

Mercredi (17 février), le jour après que Michael Saylor, PDG de MicroStrategy Inc. ait déclaré que son entreprise de logiciels cotée au Nasdaq prévoit d’acheter plus de Bitcoin (ce qui a permis à Bitcoin de franchir la barre des 50 000 dollars), le prix de Bitcoin sur le marché de la crypto-bourse Bitstamp est passé au-dessus de 51 000 dollars à 07:52 UTC avant d’atteindre 51 214 dollars, qui est le nouveau record absolu (ATH), six minutes plus tard.

Selon les données de CryptoCompare, actuellement (à 08:2 UTC le 17 février), le BTC-USD se négocie autour de 50 745 $, ce qui signifie que la capitalisation boursière de Bitcoin s’élève à environ 945 milliards de dollars. Les bitcoins ont augmenté de 2,95 % au cours des dernières 24 heures et de 75,15 % depuis le début de l’année (YTD).

Hier, Charles Hayter, co-fondateur et PDG de CryptoCompare, un des principaux fournisseurs de données sur le marché des crypto-biens, a expliqué les raisons de la flambée des prix de Bitcoin, qui ont dépassé les 50 000 dollars :

„Le projet de MicroStrategy d’acheter 600 millions de dollars de bitcoin supplémentaires marque la dernière étape de la tendance croissante à l’adoption du bitcoin par les entreprises et les institutions, qui fait grimper les prix à des niveaux sans précédent.

„Ce resserrement continu de l’offre, dû à des achats importants par les entreprises dans une perspective à long terme, survient à un moment où les frictions des investisseurs institutionnels pour s’exposer aux actifs numériques diminuent rapidement, créant une tempête parfaite pour l’appréciation du prix du bitcoin.

L’investissement récent de 1,5 milliard de dollars dans Bitcoin par Tesla pour l’utiliser comme réserve de trésorerie a légitimé encore plus le discours sur la couverture de l’inflation et le cas d’utilisation de la „réserve de valeur“ pour Bitcoin. Ce faisant, il est devenu beaucoup plus probable que d’autres sociétés suivront le mouvement, car il est plus difficile de passer pour un idiot après qu’un des entrepreneurs et des sociétés innovantes les plus prospères du monde se soit engagé de manière aussi visible en faveur de Bitcoin“.

Le prix de Bitcoin ne franchisse le niveau des 51 000 dollars

Environ une heure avant que le prix de Bitcoin ne franchisse le niveau des 51 000 dollars, Ki Young Ju, le PDG de CryptoQuant, une start-up sud-coréenne spécialisée dans l’analyse des chaînes de magasins, a souligné que le „Coinbase Premium Index“ était redevenu positif, ce qui est un indicateur haussier. Selon CryptoQuant, plus l’écart entre le prix de Coinbase pour Bitcoin (BTC-USD) et le prix de Binance pour Bitcoin (BTC-USDT) est élevé, plus la prime est importante, et donc plus la pression d’achat au comptant de Coinbase (qui est la bourse la plus populaire auprès des investisseurs aux États-Unis) est forte.

Le crypto-analyste/négociant néerlandais Michaël van de Poppe a déclaré plus tôt dans la journée que maintenant que Bitcoin a dépassé les 50 000 dollars et qu’il est médiatisé, les négociants et les investisseurs sont heureux d’acheter autant de BTC qu’ils le peuvent alors qu’ils n’étaient pas intéressés en mars dernier, où ils pouvaient avoir BTC pour seulement 5 000 dollars (ou même moins).

Holger Zschaepitz, rédacteur en chef du bureau économique et financier du quotidien allemand Die Welt et de son édition dominicale Welt am Sonntag, a présenté une mise à jour du marché plus tôt dans la journée, et a déclaré qu’il semble que les investisseurs se tournent de plus en plus vers les bitcoins plutôt que vers l’or pour se couvrir contre une inflation plus élevée.

Pendant ce temps, la dernière analyse de la start-up d’intelligence économique Glassnode montre qu'“il y a maintenant plus de 94 000 adresses #Bitcoin détenant au moins 1 million de dollars de $BTC“.

Fnally, hier, l’analyste/négociant chevronné Peter Brandt a mentionné que „Bitcoin connaît sa troisième avancée parabolique au cours de la dernière décennie“.

Partially guilty? – Alexander Vinnik is one of the main suspects in the disastrous hack of the defunct crypto exchange Mt Gox. He was notably accused of money laundering, by facilitating the concealment of bitcoins stolen from this platform in 2014. But it was for other acts of money laundering that he was tried in France last October.

A ransomware and bitcoin laundering system

Since his arrest by Greek police in 2017, Alexander Vinnik has been the subject of extradition requests from both Russia (where he is from), France and the United States . It was finally France that obtained the transfer of the suspect to its soil from Greece, in early 2020.

The trial of Alexander Vinnik thus opened in Paris on October 19 . As summarized by the Russian newspaper The Moscow Times , the charges against this computer developer concerned the use of ransomware to obtain bitcoins (BTC) and then their laundering through the exchange platform BTC-e .

The one who has always presented himself as a “simple technical operator” of the BTC-e platform has just received the verdict of his trial, which will be described as half-hearted .

Sentencing to 5 years in prison

Even though there was not sufficient evidence against Alexander Vinnik to support the charges of participation in the use of the ransomware called Locky , the Russian national was convinced to have participated in and facilitated the laundering of the 135 million euros hijacked by these cyber attacks.

The now 41-year-old man, already in detention, was therefore sentenced to 5 years‘ imprisonment and a fine of 100,000 euros for money laundering in an organized gang.

If Alexander Vinnik had been extradited to the United States rather than France, things could have turned even worse for him. He is indeed facing 21 charges , ranging from identity theft to facilitating drug trafficking, including money laundering.

In the reverse, is, like the the souhaitait, carry Extrade été en Russie , il n’y serait que d’une room fraude de 9 500 euros . Suffice it to say that he would have come out free.

Oasis Network, focusing on privacy, promises to make unsecured loans at DeFi easy.

Oasis Labs announced the successful launch of its Oasis Network mainnet, with more than 70 independent validators already live.

Oasis is a privacy-focused layer one network designed to support decentralised applications that demand 1000 transactions per second performance. In June 2018, Oasis raised $45 million from large crypto companies including A16z, Binance Labs, Pantera and Polychain. Oasis allows data to be encrypted and the privacy policies surrounding its use to be enforced through smart contracts.

Oasis Labs says that its „confidential computing“ functionality allows network nodes to process encrypted data to ensure privacy for a wide range of processes, from credit history checks to genetic research. An announcement on 19 November explained:

„The Oasis Network can support a new generation of privacy-aware Bitcoin Trend App applications that respect user data preferences by design and ensure that each individual receives fair compensation for their data. They can earn rewards by betting their data with applications that want to analyse it or control how their most sensitive information is consumed by the services they use“.
The Oasis team introduces the network’s privacy protocols to facilitate the creation of under-secured credit products within the DeFi sector. The network is said to have a greater capacity to allow credit checks, as it ensures the privacy of confidential financial or personal data, allowing loan applicants to establish their creditworthiness with lenders.

Most of the existing credit products within DeFi offer over-guaranteed loans, although projects, including Mainframe, are also making efforts to introduce under-guaranteed loans.

The announcement notes that industry leaders DeFi, Chainlink and Balancer, recently joined the Oasis Network. Oasis Labs also believes that its secure architecture could also facilitate the creation of decentralized private exchange platforms, including automated market makers such as Uniswap.

According to Oasis, „hundreds“ of partnership projects are already being built on the network, including a „genome sequencing first in privacy“ company with Nebula Genomics and CryptoSafe Alliance, or CSA, led by Binance.

Last month, Oasis announced that Nebula Genomics would use its „Parcel“ data governance API product to allow genomic data to be analyzed within an isolated computing environment.

The project aims to reduce the risk of consumers‘ genetic data being compromised by the violation of centralised databases. Parcel also provides secure data storage and tamper-proof access history records for consumers.

Announced in August, CSA is a platform designed to facilitate the private exchange of threat intelligence data between cryptosystems exchanges. CSA uses Oasis‘ confidential intelligence contracts to ensure that confidential data belonging to participating entities remains private within the network.

Ny Mac-opdatering giver brugerne ikke plads til at undslippe dataindsamling

• Apples seneste opdatering, Big Sur, gør en funktion, der logger enhedsaktivitet til offline (og online) applikationer praktisk talt umulig for privatlivsløsninger at omgå.
• Overvågningen er endnu et eksempel på Apples fortrolige designvalg på trods af virksomhedens bestræbelser på at præsentere sig som en allieret til privatlivets fred.
• VPN’er og andre firewalls kan ikke omgå funktionen.
• Sikkerhedsforskere foreslår, at brugere, der holder af deres digitale privatliv, udforsker andre open source-alternativer.

Den 12. november klagede Mac-brugere på, at deres computere fungerede trægt. Denne træghed faldt sammen med frigivelsen af ​​Big Sur, den seneste Mac-opdatering fra Apple.

Efter opdateringen blev frigivet, forstyrrede en teknisk fejl de servere, som Apple bruger til OCSP-anmodninger, de datapakker, der Bitcoin Profit bekræfter en computers SSL-certifikat, når den får adgang til onlineapplikationer. Apple-enheder lukkede ned, fordi disse OCSP-anmodninger ikke nåede Apple-servere

Da nogle brugere kiggede tættere på, blev det meget klart, hvorfor enhederne mislykkedes, når OCSP-serverne svigtede: Hver gang en bruger åbner en applikation (endda en offline), mærkes og spores denne handling af Apples OCSP-servere.

Denne funktion blev introduceret i Apples Catalina-opdatering, men visse værktøjer (som Little Snitch) kunne bruges til at omgå den. Nu med Big Sur er der ingen praktisk måde for gennemsnitlige Mac-brugere at forhindre funktionen på.

Apple har udråbt sig som at skubbe privatlivets fred som kernen i sin mission, måske mest offentligt ved at afvise retshåndhævelseskrav om at låse op en af ​​San Bernardino, Californien, skytterens iPhones efter angrebet i december 2015.

Men disse nye afsløringer demonstrerer nogle af de iboende fejl i centraliseret dataindsamling – du skal stole på Apple for ikke at dele disse oplysninger (eller stole på, at de ikke tvinges til at afsløre dem til et regeringsorgan). I dette tilfælde er Apples siloing af data gennem Big Sur muligvis ikke engang det primære problem, fordi disse OCSP-anmodninger transmitteres ukrypteret, hvilket betyder, at indholdet kan læses af enhver overvågningspart, der opfanger dem.

Således, hvis Mac-brugere vil komme ud under Apples øje, bliver de nødt til at undersøge alternativer.

Mac-opdatering muliggør offline aktivitetslogning

„På moderne versioner af macOS kan du simpelthen ikke tænde for din computer, starte en teksteditor eller eBook-læser og skrive eller læse uden en log over din aktivitet, der overføres og lagres,“ skriver hacker og sikkerhedsforsker Jeffrey Paul i en blogindlæg.

Paul fortalte CoinDesk i en e-mail, at han ikke synes, „Apple har dårlig hensigt her“, men at dets mål er at overvåge malware og anden ulovlig software på dets enheder.

Problemet er dog, at disse OCSP-anmodninger er ukrypterede og så „sårbare over for passiv overvågning.“ Dette efterlader dataene åbne for indsamling og parsering i hænderne på „store passive overvågningsorganisationer“ såsom U.S.National Security Agency (NSA).

„Dette er selvfølgelig frygtelig praksis, og på trods af at de er industristandarden, burde Apple vide bedre, da de er kryptografiskeksperter (som driver deres egen certifikatmyndighed og regelmæssigt bruger relativt avancerede kryptografiske værktøjer som klientcertifikater og cert pinning)“ Skrev Paul via e-mail.

Telemetri er en diagnostisk proces, hvor servere sporer, hvordan en enhed bruges. Paul sagde, at problemet med Apples system her er, at fordi disse data ikke er krypteret, kan tredjeparter læse dem. Enhver enhed, der bruger disse kommunikationslinjer, kan se, hvilke applikationer nogen bruger, og hvornår de bruger dem.

”Den virkelige privatlivsrisiko her er ikke, at Apple muligvis indsamler disse data. De er sandsynligvis ikke, da jeg mener, at dette er et forsøg fra Apple for at forhindre malware i at være i stand til at udføre på deres platform. Problemet er, at det fungerer som * utilsigtet * telemetri til enhver, der lytter på ledningen, som i USA er enhver større internetudbyder og det nationale militær, ”fortsatte han.

Denne form for bekymring har ført til argumenter mod centraliserede servere for sporing af kontakter i EU. De har også opfordret til de seneste presser på mixnet, der blander netværkstrafik specifikt for at undgå passiv metadataobservation.

Apples enheder har altid været en slags muret have. Applikationer og software fra for eksempel ubekræftede udgivere skal godkendes manuelt af brugerne. Det tilsyneladende mål med sådanne kontroller er at beskytte brugeren, men som Cory Doctorow for nylig understregede over for CoinDesk via e-mail, kan disse kontroller tilsidesætte agenturet i visse scenarier (for eksempel når Apple

Stanley Printmiller last demonstrated in 2008 that he “can handle a crisis”. Now the former head manager of the Soros hedge fund Quantum Fund sees the next crisis approaching – and Bitcoin as a possible hedge against it.

Henry Druckermiller has opened up to Crypto Wealth. Compared to the US news broadcaster, the founder of the former hedge fund Duquesne Capital granted digital gold the potential to be an attractive store of value, especially for millennials.

The almost 12-year history of Bitcoin has shown that the demand for digital gold is higher than the supply.

The Bitcoin story is very simple. It’s about supply and demand. Bitcoin’s supply is growing about 2.5 percent annually, and demand is growing faster than that.

The self-proclaimed dinosaur holds Bitcoin himself to protect himself against the devaluation of the US dollar. However, gold still makes up the largest part of his „dollar decline basket“.

Good for Bitcoin? Corona vaccine could overheat economy

The self-proclaimed dinosaur holds Bitcoin himself to protect himself against the devaluation of the US dollar. In view of the macroeconomic situation, printing miller is inevitable that inflation will come:

Look at the extraordinary measures the Fed has taken […]. I think it is very likely that we will have inflation in the next five or six years. In a year or two – especially with a vaccine – the economy could be very hot. At the same time, all stimulus packages are in the pipeline and the strained supply chains between the US and China.

Druckermiller justifies this with the fact that gold has already proven itself as an asset and protection against inflation for 5,000 years. However, he admits that Bitcoin is potentially the more lucrative bet against the US dollar:

I hold a lot, a lot more gold than Bitcoin. But if the gold bet works out, the Bitcoin bet probably works out even better because it is thinner, more illiquid and has a better data base.
