Spot Bitcoin ETFs in the US find buyers after several weeks of capital outflows. In three sessions, they attracted 1.07 billion dollars, thereby erasing losses recorded since early October. However, this investment recovery is not enough to support prices. The market remains under pressure as investors watch the upcoming Federal Reserve moves. This discrepancy raises questions about the strength of the current rebound.

The computing power of the Bitcoin network has reached the threshold of 1 zettahash per second, its highest level in nearly seven months. This rebound strengthens the protocol's security, but it also signals a new increase in difficulty that could reduce the revenues of less competitive mining companies.

Arf will provide RLUSD to payment companies on the XRP Ledger, with repayments in one to five days. The native XRPL lending is not yet activated.

The hacker behind the massive Drift Protocol breach has just injected over $122 million in ETH into Tornado Cash. While Arkham traces this unprecedented scale laundering, Binance founder Changpeng Zhao (CZ) reminds a brutal reality: 100% security does not exist in the crypto world.

Bitcoin approaches a decisive threshold as markets await new American inflation indicators. After several positive sessions, inflows into spot ETFs have sharply slowed, reducing support for prices. On Friday, PMI indices and household inflation forecasts could change investor expectations before the next Federal Reserve meeting. Maintaining the 80,000 dollar level will therefore also depend on these economic signals.

A study published by the Bank for International Settlements estimates that Bitcoin does not have the necessary architecture to become an everyday currency.

Ethereum researchers want to reduce the finality time of transactions from 16 to 4 minutes. Behind this technical improvement is a concrete economic issue: to allow transfer services to mobilize less capital while waiting for the final confirmation of operations. For now, the project is still under study and does not plan any deployment date.

Ken Griffin believes investors are "almost certainly" in an AI-related bubble. The founder of Citadel does not, however, question the technology itself. His concern is mainly about the amounts invested, the cost of GPUs, and the difficulty many companies have in turning their expenses into productivity gains. For him, a correction could eliminate many players while allowing the future giants of the sector to emerge.

The rise in bond yields in the euro area revives the debate on the "vicious circle" linking the health of banks to that of states. European institutions hold 4,300 billion euros in sovereign debt, but their capital reserves are stronger than during the crisis of the 2010s.

Bitcoin briefly approached 84,800 dollars on Wednesday before erasing almost all of its gains. BTC was trading around 82,800 dollars on Thursday, just above the closely watched 82,500 dollar support. The reversal is not only due to concerns about artificial intelligence. The war with Iran keeps oil at high levels, while US inflation remains at 3.7% and the Fed meets on October 28. Meanwhile, Bitcoin ETFs have nevertheless attracted more than one billion dollars in three sessions.

Dogecoin Labs wants to give a new dimension to DOGE. Created with the Dogecoin Foundation, the company brings together the MyDoge wallet, the DogeOS platform, and Such App, dedicated to merchant payments.

The cryptocurrency market is recovering after several difficult sessions. On Wednesday, Bitcoin reached a two-week high, triggering a strong rise in Strive and Strategy stocks. Both companies, which hold significant cryptocurrency reserves, directly benefit from this recovery.

According to Glassnode, this situation is currently slowing Bitcoin's progress to around $87,700. Holders who entered the market recently exert selling pressure when prices reach their breakeven threshold. Meanwhile, on-chain data reveal several support levels likely to influence the market's next movement.

Solana replaced TowerBFT with Alpenglow on its mainnet on October 21, in its most significant consensus change since launch. The new protocol targets a finality close to 150 milliseconds, compared to about 12.8 seconds previously, but part of the planned architecture is still to be deployed.

This operation is part of a series of movements that raise questions about the fate of the funds and the missing private keys.
