According to CoinMeta, Bitcoin has performed the best in the past week, with its price breaking through $75,000, and market sentiment shifting from fear to greed within a single day. The Treasury Department's buyback program triggered short-selling liquidations, leading to a rapid change in market sentiment. Although the policy will not take effect until three weeks later, this unexpected announcement by the Treasury Department sparked a strong rebound for Bitcoin, with its value rising by about 20% over the past seven days. Ethereum also saw an increase, and the total market value of the crypto industry rebounded to over $2.5 trillion. Treasury Secretary Scott Bessent announced an expansion of the long-term bond buyback program from $2 billion to at least $4 billion, although this change will not come into effect until September 9th. The market reacted quickly to this policy, with the Fear-Greed Index jumping from 46 to 62 within a day and further rising to 72 on Friday.
