Exactly, Jahan.

By now a cryptoinvestor should had already performed a DD, research - identified HQ cryptopicks and acquired them.
You should have a reasonable price targets, valuations for the projects you have picked - so you know the true value of it.
You should not sell unless you are at margin or speculating. But a good speculator knows how to stop losses and be flexible for any type of the market.
Remind it here again: Just HODL (hope you are clever enough not use leverage bets and critical to your financial stability funds while investing in cryptos) - if you are for long-term journey. Trade actively - if you are a trader.
We believe - the real game is to HODL and accumulate gradually on deeps. ;-) (only for HQ cryptoprojects)
