In April 2023, the cryptocurrency market experienced a significant rebound, with Bitcoin breaking through $83,000 and Ethereum returning above $1,600. AI concept tokens led the rally with a 15% increase. The main driving factors include: 1) The Trump administration's suspension of additional tariffs, alleviating concerns over trade conflicts; 2) Market expectations that global central banks will maintain accommodative policies, increasing liquidity; 3) The recovery of the U.S. tech sector boosting sentiment for crypto assets. However, the rebound is driven by sentiment and still faces macro risks in the short term (such as Federal Reserve policies and the potential for black swan events involving Satoshi Nakamoto's holdings) as well as technical resistance levels (with BTC resistance at $81,211). Investors should be cautious of volatility and avoid blindly chasing highs.
