Bitcoin retreated to about $64,000 after a fresh attempt to clear $65,400 failed, giving back part of a rebound that began after last week's monthly low of $62,200. The move followed a volatile stretch in which BTC recovered from $63,800 to above $64,000, climbed toward $65,000, slipped after the CLARITY Act's latest setback in the US Senate, and then got another lift from weaker US jobs data on Friday. Bears later pushed it down to $63,800 as Peter Schiff urged investors to sell, leaving Bitcoin's market capitalization below $1.290 trillion and its dominance (share of total crypto market value) above 57% on CG. Altcoins (crypto tokens other than Bitcoin) also weakened, with Ethereum down 2.5% to below $1,900, XRP at a 21-month low just above $1.00 and close to falling below that level for the first time since November 2024, ZEC down almost 5% to under $490, ADA off 4% to below $0.19, and Pi Network's native token breaking under the $0.09 support after another near-5% daily drop. BNB, TRX, HYPE, DOGE, RAIN, XMR, LINK, MNT and WLF posted gains, but the total crypto market cap fell by around $40 billion to $2.250 trillion.
