Odaily reports that last week, Bitcoin briefly reclaimed the $90,000 mark, and is now in a new volatility range between $85,000 and $92,000, with uncertainty continuing to loom over the market. At the beginning of last week, the price soared due to speculation about the US strategic Bitcoin reserve and the White House cryptocurrency summit, but after the news was confirmed, traders adopted a "sell the news" approach, and the market quickly erased the gains. The options market also exacerbated the volatility last week, with $30 billion worth of Bitcoin and Ethereum contracts expiring on Friday, further driving price fluctuations. Many traders suffered significant losses last week, with actual losses to market participants reaching $818 million per day, and March 28 and March 4 being among the single largest loss events of the period. The current macroeconomic indicators do not clearly indicate the future direction of the market. Meanwhile, the US Securities and Exchange Commission's cryptocurrency working group will hold a roundtable on March 21 to clarify the security status of digital assets, indicating that regulatory guidance will shift towards a more structured approach. In Japan, the Liberal Democratic Party is implementing tax reforms favorable to cryptocurrencies, reducing the capital gains tax to 20% and classifying cryptocurrencies as a unique asset class. The reform also proposes to defer taxes on cryptocurrency-to-cryptocurrency swaps and to apply equal tax treatment to derivatives, in order to encourage digital asset investment.
