1st step: when bloodbath starts ... you start accumulating slow & invest little.
2nd step: continue adding.
3rd step: when there is extreme panic in market, you accumulate huge.
4th step: wait & watch. take profit as it takes U turn making your investment gain massive return.
sounds simple isn't ? but this requires discipline.
note: this doesn't apply across all types of crypto. Dyor and don't jump into new projects.
