Bitcoin traded near $77,300, maintaining its 22% weekly gain, while XRP, up 48% to $1.48, and Zcash, up 70% to $838, steadied after significant weekly surges. The rally was driven by factors including a $4 billion U.S. Treasury bond buyback expansion, White House support for crypto, Trump's backing of the CLARITY Act, and a Grayscale spot Zcash ETF filing. Attention now turns to Fed Chair Kevin Warsh's debut at the Jackson Hole symposium, where his stance on rates will be key.
