After Bitcoin's integration with the US stock market, many strategies for making money in the crypto space may not work as well. It might be worth trying to change your approach:

1. Switch from US dollar-based to cryptocurrency-based, Bitcoin has a perpetual slow bull trend;

2. Lower your return expectations; high volatility will disappear. Achieving several times the return in a year is unrealistic, but doubling your investment in a year is feasible;

3. Learn to go long and reduce short selling; those who have traded US stock index futures will have a profound understanding of this;

4. It is very unlikely to see a significant drop; no matter how much it falls, there will always be new highs.
