QUBIC, the token of the Qubic blockchain, can be bought on nine active exchanges, by card through two payment providers, and on decentralized platforms. Your options depend on where you live. In Europe, two routes are authorized under MiCA. Most exchanges exclude the United States and Canada. As of October 4, 2026, Cointribune checked each platform’s fees, identity verification (KYC) and excluded countries. Four platforms still named in Qubic’s official lists have closed or no longer offer the token.

Ethereum prepares to increase its gas limit from 60 to 200 million per block as part of the Glamsterdam upgrade. This increase represents a factor of 3.3, not 33, but it currently only applies to test networks, with no date set yet for the mainnet.

Nine crypto organizations have created the Quantum Alliance to define common standards for protecting blockchains against future quantum computers. The group estimates that 6.04 million BTC already have a visible public key, but these funds cannot be stolen with machines available today.

While Bitcoin ETFs record over $82 million in outflows in 24 hours, the chart pattern signals a bullish accumulation triangle that could soon push BTC towards $90,000.

The rise of artificial intelligence raises questions about investments, public debt, and financial markets. For Arthur Hayes, chief investment officer at Maelstrom, the bursting of this bubble could benefit bitcoin. According to him, the bailout plans for the affected companies would increase the money supply and favor safe-haven assets. However, this bullish outlook faces several obstacles, including risks linked to quantum computers and capital outflows from US spot ETFs.

A slight increase in interest rates on bank deposits could slow the growth of stablecoins. This is the finding of a study by the Bank for International Settlements (BIS), which highlights competition between bank savings and these cryptocurrencies pegged to traditional currencies. However, the effect varies depending on the players: Circle's USDC appears more sensitive to this competition than Tether's USDT.

Mike McGlone, strategist at Bloomberg Intelligence, believes bitcoin could fall back to 10000 dollars if American stocks lost 20%. Ki Young Ju, founder of CryptoQuant, rejects this projection and rather sets a theoretical floor around 30,000 dollars, due to institutional purchases and on-chain valuation.

Inflation is pushing many investors to seek assets capable of preserving their purchasing power in the long term. Bitcoin holds a special place in this debate thanks to its limited supply, capped at 21 million units. However, holding this asset does not guarantee a positive return. Borrowing costs, forgone income, and derivative fees can reduce gains. When rates remain high, these expenses become a determining factor in assessing the true profitability of an investment.

Christine Lagarde believes the eurozone economy is resilient to global shocks and confirms the progress of the digital euro project. Its public arrival, however, is not imminent: the ECB plans an internal pilot in the second half of 2027 and could only proceed with a first issuance in 2029, subject to prior adoption of the European regulation.

Visa moves stablecoins from the lab to commercial operations. The payment giant has just put Visa Direct's stablecoin capabilities into production with Inyo Global. Eligible businesses will notably be able to use USDC to pre-finance their cross-border payments 24/7. The change comes as Visa's stablecoin settlements now exceed an annualized pace of $20 billion.

Charles Hoskinson believes that Cardano will be complete after the deployment of Leios. For the network founder, this upgrade must bring the processing capacity that the blockchain still lacks. But between technical ambitions and field reality, several steps remain to be taken.

Claude just solved in less than 30 minutes a cryptographic puzzle that had been lingering for about 25 years. Anthropic's AI model found the origin of five numbers provided by the NSA for certain elliptic curves standardized by NIST in 2000. Long suspected of possibly hiding a backdoor, they ultimately came from an old pseudo-random generator fed by timestamps from 1997 and 1998.

Vitalik Buterin pushes the privacy of his AI agents very far. The co-founder of Ethereum has just unveiled a "paranoiac mode" combining Tor, private payments via zkAPI, dummy network traffic, and local rewriting of prompts. Each conversation goes through a different Tor circuit. Even the payment to the AI provider is designed to no longer directly reveal the user’s identity.

XRP is trading around 1.33 dollars, 62.5% below its January 2018 peak, while Bitcoin and Ether have largely surpassed their levels from that time. This underperformance does not mean that all its holders have lost money: it mainly concerns those who bought close to the peaks, while the increase in supply has diluted the value represented by each token.

Sending 200 dollars via networks using stablecoins costs about 2 dollars, compared to 12.72 dollars with traditional channels. This is according to the quarterly report from Borderless.xyz. In addition to reducing fees, these solutions speed up transfers: a few minutes are enough where banking circuits often take several days.

Bitcoin must reclaim its 20-month moving average, located around 87165 dollars, to strengthen the scenario of a new all-time high, according to CryptoQuant. However, this technical signal remains a condition, not a promise of increase, while BTC is still trading near 82000 dollars.

Friday, October 16, the National Assembly adopted an amendment that could change crypto taxation in France. The text targets conversions into regulated stablecoins, even when investors do not recover their gains in euros. Led by Nicolas Sansu and sixteen deputies, this measure is part of the debates on the 2027 budget. However, its final adoption remains uncertain, as several parliamentary stages still need to confirm this new tax rule.

Twist on the Fed! The probability of a rate hike in October collapses from 48% to 13% on Polymarket. Between purged panic and massive accumulation, is Bitcoin preparing for the big shock of the fourth quarter?

Binance plans to expand its offer to stocks from Hong Kong, South Korea, Taiwan, and Brazil, while Binance.US would seek to raise up to 100 million dollars. These distinct projects illustrate the same strategy: to go beyond the crypto market alone to build multi-asset financial platforms.

Bitcoin brushed $80,000 on Thursday before bouncing back above $82,000. While buyers managed to defend this key threshold, Glassnode notes a sign of fragility: buy orders supporting the price are becoming scarce below this symbolic level. A situation that deserves attention, as tensions over US inflation continue to weigh on markets.

Russia will close an important door of its crypto market. From July 1, 2027, two individuals will no longer be able to buy or sell bitcoin or other cryptocurrencies directly between themselves. The Bank of Russia just confirmed this in an FAQ published on October 12. Transactions will have to go through an authorized intermediary, including a broker or a platform registered with the regulator.

Bitget has rolled out a series of limited-time promotions across Cash Plus, Simple Earn, BGSOL and BTC. The campaigns offer additional returns on assets users already hold, combining boosted interest rates, balance-based bonuses and incentives linked to futures trading. Some offers promise annual percentage rates (APR) of up to 15%, although eligibility rules and deposit limits apply.

Three members of the Canadian Armed Forces are among seven men charged after the alleged kidnapping of the owner of a crypto platform in Toronto. The suspects reportedly tried to gain access to his digital assets and professional security systems, but the police have not confirmed any theft of cryptocurrencies.

An alleged scammer is among the main victims of recent thefts affecting Ledger wallets. Chainalysis reveals on October 15 that an operator suspected of organizing a scam involving fake paid tasks lost over 60 bitcoins, approximately 4.8 million dollars. The funds had been distributed across three addresses before being stolen on October 9. The case takes an unexpected turn: the stolen bitcoins are themselves reportedly from a scam.

The bitcoin market faces a new challenge that goes beyond price fluctuations. Strategy, Michael Saylor’s company known for its substantial cryptocurrency reserves, risks losing its place in some major stock indices. On Thursday, MSCI approved new rules targeting companies whose activity resembles an investment vehicle rather than a traditional business. This decision could alter demand for Strategy shares and complicate its future purchases.

Google demonstrated on its Willow processor a method that greatly reduces errors during the creation of a component essential to universal quantum computing. This advance brings research closer to useful quantum computers, but it does not yet allow breaking the signatures that secure bitcoins.

An investigation by the Wall Street Journal connects Tether to $6.3M paid to Nxum, a company co-founded by Bo Hines, former crypto adviser to Donald Trump.

The crypto market regained momentum in the third quarter of 2026 after several months of decline. According to the latest CoinGecko report, its total market capitalization increased by 39.6%, driven notably by Ethereum and flows into Bitcoin ETFs. However, this recovery is not accompanied by an equivalent return in trading activity. Spot volumes are declining, while leveraged positions are rising. This discrepancy raises several questions for the coming months.
