Trading rules for supporting a family by trading stocks for 30 years, I think they also apply to the crypto circle:
1.
Empty your position after making a big profit
2.
Empty your position after losing for three consecutive days
3.
Do not trade on divergent days
4.
Do not chase after opening more than 5% higher
5.
Do not chase after a huge volume at a high level
6.
Buy low in a weak market, relay in a strong market
7.
Do not go all in without 100% confidence.
