Bitcoin extended its rally on Tuesday, hitting the $80,000 psychological level for the first time since May 4. The rally comes as improving liquidity expectations continued to lift the broader cryptocurrency market. Bitcoin has gained nearly 30% in the last week, while Ethereum has risen more than 25% and XRP has advanced almost 30%. The rally gained momentum after the U.S. Treasury announced plans to double the size of certain debt buyback operations. The decision eased liquidity concerns and strengthened demand for risk-sensitive assets. With Bitcoin still flying, investors are now watching whether it can extend its rally and reach…

Bitcoin’s broken back above US$80,000, up 27.5% over the past week and currently trading at US$80,684. Bitfinex reports the rally came alongside the biggest short-liquidation event on record, with roughly US$3 billion in shorts wiped out on 19–20 August. The catalyst was a US Treasury announcement on expanded buybacks of longer-dated government debt, which pushed Bitcoin out of its US$62,000–US$65,000 range. Ether joined the rally too, up more than 32% since 19 August, while analysts are watching US$86,500 as the next resistance level for BTC. Bitcoin has broken through the US$80k (AU$111.8k) barrier again, gaining 4.3% over the past 24…

The Hyperliquid Policy Center filed a 15-page comment letter with the CFTC and SEC on 24 August, asking them to classify perpetual contracts by structure and not by the asset they reference.

Hyperliquid is not currently available to persons in the United States, and the group says its work covers onchain markets “including those available on Hyperliquid”. Hyperliquid Policy Center asked the SEC and the CFTC to treat equity perpetual contracts as security futures.  In…

The group said a second command could replace the transaction held in memory without opening a new review, leaving the original details on screen while the device…

A newly merged Ethereum proposal would retire the network’s 512-validator sync committee, remove its rewards, and make the current Altair light-client interface obsolete by replacing it with offchain zero-knowledge proofs.The Draft EIP-8390 estimates that deleting the committee’s reward weight would reduce annual consensus issuance by roughly 33,800 ETH.Ethereum would give up an in-protocol mechanism that lets lightweight clients follow the beacon chain before the proposed replacement proving service, migration interface, and economic support have been specified.A sync committee is a 512-validator sample whose messages give light clients a compact way to track Ethereum without processing the full validator set.The proposal…

Reported losses from deepfake scams in 2026 have already exceeded last year’s total by 263%, according to TRM Labs, highlighting a growing crypto security problem in which attackers increasingly manipulate authorized users rather than break blockchain code.The blockchain intelligence firm’s new AI-in-Crime Adoption Index classifies scams as the only crypto-crime category where artificial intelligence has reached a “Mature” level of adoption.TRM said reports involving scammer-side use of AI, including deepfakes, chatbots and AI-powered lures, have risen roughly 13-fold since 2022.The shift exposes a weakness that traditional smart-contract security does not address. An exchange account can be properly authenticated, a hardware…

Fidelity’s FETH and FSOL staking plans give its Ethereum and Solana exchange-traded products authority to stake up to 100% of their crypto under normal conditions, while pairing that ceiling with a layered plan for meeting redemptions when network exits take too long.The matching framework appears in Aug. 21 prospectuses for the Fidelity Ethereum Fund, or FETH, and Fidelity Solana Fund, or FSOL. Neither fund has a minimum staking requirement, and sponsor FD Funds Management can keep ether or SOL unstaked for foreseeable redemptions, expenses, asset protection and its liquidity program.The 100% figure is an authority ceiling, not evidence that both…

The EU regulation adds “NoOnecrypto INC.” to Annex XLV Part A from that date under a…
