On March 27th, BTC broke through $87,500 and is now reported at $87,360. The rally was affected by the US Senate's vote to repeal the Biden administration's crypto tax rules. The bill is expected to be signed by Trump and become the first formal cryptocurrency bill in the United States, bringing good news to the market. Trump also publicly supported Bitcoin, praised the Bitcoin Act advocate Cynthia Lummis, and stressed that it will promote the United States to become the global cryptocurrency capital. The market responded positively, and BTC rose in response. Bitunix analysts suggest: BTC short-term support: $85,500, pressure level: $89,000. If it breaks through $89,000, it may test $90,500; if it falls below $85,500, or pull back to $83,000. Long-term investors can pay attention to Bitcoin ETF and regulatory policies, and gradually increase their long-term positions.
