Bitcoin + 4 iron laws, no exceptions so far:

1. Halving once every four years

2. A big bull market starts half a year after halving

3. The bull market ends one and a half years after halving, and a sharp drop begins - the best time to escape the top

4. The sharp drop continues for 1 year and bottoms out, with a drop of 80% - the best time to buy the bottom

When the Bitcoin bull market rises too much, funds will naturally flow to the copycats, and the copycats will rise when the trading volume is large (unless Bitcoin does not have a bull market)
