In April 2023, the crypto market experienced a significant rebound, with Bitcoin surpassing $83,000 and Ethereum returning above $1,600, while AI concept tokens led the surge with a 15% increase. The main driving factors include: 1) The Trump administration suspended additional tariffs, easing concerns about trade conflicts; 2) The market anticipates that global central banks will maintain loose policies, enhancing liquidity; 3) The recovery of the technology sector in the U.S. stock market boosted sentiment for crypto assets. However, the rebound is driven by sentiment, and in the short term, it still faces macro risks (such as Federal Reserve policy and unknown black swan events involving Satoshi Nakamoto) and technical resistance levels (BTC resistance at $81,211). Investors should remain cautious of volatility and avoid blindly chasing highs.
