According to CoinMeta, Bitcoin ($BTC) has wiped out three months of losses in just one week, with the price breaking through $80,000 earlier on Tuesday for the first time in 15 weeks. Over the past eight days, Bitcoin has risen by 28%, with its total market value increasing by approximately $350 billion. At the same time, crypto-related stocks have also seen significant gains: MicroStrategy ($MSFT), a company in the sector, has risen by 36%, Circle has risen by 43%, Coinbase has risen by 16%, and Robinhood has risen by 12%. The rise in Bitcoin prices is related to the U.S. Treasury Department's announcement last week to increase the maximum scale of its long-term bond repurchase operations from $2 billion to $4 billion. Treasury Secretary Scott Bessent stated that he has a “strong toolbox” to deal with rising bond yields, which further encouraged bullish sentiment towards Bitcoin. Markets expect that more liquidity will drive up the prices of digital assets.
