#btc# #比特币BTC# 4 rules of Bitcoin, without exception:

1. Halving occurs every four years
2. A big Bull Market starts six months after each Halving
3. The Bull Market ends one and a half years after each Halving, starting a big dump - the best time to exit at the top
4. The big dump lasts for 1 year, hitting a bottom with an 80% drop - the best time to catch the bottom
