The most reliable strategy right now may be:
1. Don't exceed 30% position before the tax deadline;
2. Keep an eye on Bitcoin at 78,000 and Ethereum at 1,750, these two critical lines;
3. Only consider altcoins with a daily trading volume over 50 million;
4. Save enough ammunition until mid-April, when the positions that should explode will have exploded, and the paths that should be taken will have been taken, perhaps you can pick up some bloody chips.
