This is a time when emotions play against you.
1) If you have liquidity, buy if your crypto fell a lot, this is a good price.
2) If you don't have capital and there is no risk of liquidation, close and come back the next day or when you see green.
3) You always have to invest money that you are willing to lose. That way, nerves will never play against you.
This is going to be a good year for crypto to use your head and not make bad decisions that you will regret later.
