Four iron rules of Bitcoin during a bull market, with no exceptions so far:
1. Halving occurs once every four years
2. A big bull market starts six months after halving
3. The bull market ends one and a half years after halving, followed by a sharp decline — the best time to sell at the peak
4. The sharp decline lasts for 1 year and hits the bottom, with an 80% drop — the best time to buy at the bottom
When Bitcoin's bull market rises significantly, funds will naturally flow to altcoins. When the trading volume of altcoins increases, they will rise (unless Bitcoin does not enter a bull market)
