Bitcoin's Rapid Ascent Stalls Near $79,000 as Overbought Signals Flash Red

Bitcoin's rapid ascent stalled near $79,000 on Wednesday, just a day after it touched an all-time high of over $81,000. The price surge was driven by Treasury bond buybacks and forced short covering, which has seen the largest cryptocurrency climb from the mid-$60,000s in under a week.

The rally has been fueled by investors' appetite for scarce assets following the US Treasury's decision to double its purchases of longer-dated government bonds. As a result, billions of dollars in bearish bets were wiped out, and open interest in Bitcoin-denominated futures fell to a five-month low.

However, analysts are warning that Bitcoin faces a higher bar to clear after its strongest weekly rally in years. Daniela Hathorn, a senior market analyst at Capital.com, cautioned that the daily RSI reached about 84 on Tuesday, a reading that normally marks an exhausted move rather than a fresh one.

The upcoming Jackson Hole speech by Federal Reserve Chair Kevin Warsh on Friday morning is expected to test crypto momentum. With traders having almost no policy record to price against, the speech has become a two-way risk for both crypto and the dollar.
