Trump also hinted at regulating Hyperliquid, the decentralized exchange that's been garnering popularity among traders as the home base of "perpetual futures" trading. The Hyperliquid token rose about 20% over the past 24 hours, according to CoinGecko data.A retreat in Treasury yields also helped to boost trading in the iShares Bitcoin Trust ETF (IBIT) which was more than 4.5 times the 30-day average even before the Hyperliquid headlines. Bitcoin volatility measured by Volmex Labs' BVIV Index rose to above 43.5 after hitting a year-to-date low of 35.5 Friday.Stock Chart IconStock chart icon ETF The US Treasury's announcement of a significant increase in the buyback of 20-year and 30-year bonds sent yields significantly lower. And it raises the attractiveness of higher-risk assets like Bitcoin to investors, according to Charlie Hayward, APAC regional director at RootstockCollective. Bitcoin's move reflects an alignment of macro and policy catalysts, according to Max Stuedlein, head of Partnerships at Sygnum APAC."The Treasury's decision to double its buybacks of long-dated government debt is aimed at addressing long-term yield concerns, where borrowing costs have been rising on concerns over US debt levels and partial crowding out by debt issuances of hyperscalers," he said.Geoffrey Kendrick, global head of digital assets research at Standard Chartered, noted that the announcement from the US Treasury to increase the size of back-end support "is exactly the type of thing Bitcoin loves." "Investors should now be positioning for a move to $100,000 by year-end 2026," Kendrick added. "The moves in crypto have been so big in the last couple of days that it's triggered the second-largest ever short liquidation in history, " said Thomas Lee, co-founder and head of research at Fundstrat, adding that the sizable moves have pushed ether to a three-month high. Ether rose about 19% in the past seven days to $2,251, according to CoinGecko.Bitcoin had been stuck between support around $62,000 and resistance at $66,000 in the past six weeks, which became "rather frustrating for crypto traders, as the lack of volatility, even after bitcoin has effectively halved from its all-time high hit last October," said David Morrison, a senior market analyst at Trade Nation.
