In recent times, the cryptocurrency market has seen a strong rebound, with Bitcoin leading the charge and driving up mainstream cryptocurrencies such as Ethereum and Solana, shifting market sentiment towards optimism. The rebound is primarily driven by the following factors:

1. **Easing macro policies**: Rising expectations for interest rate cuts by the Federal Reserve are alleviating liquidity pressures.

2. **Increased institutional participation**: Inflows into Bitcoin spot ETFs and traditional financial institutions' involvement (such as BlackRock's RWA tokenization) are boosting confidence.

3. **Technological upgrades and ecosystem development**: Ethereum Layer 2 scaling and the active Solana ecosystem are pushing the market.

In the short term, the rebound looks promising, but it is important to be cautious of regulatory policies and the risks of high market volatility.
