in the world of trading the key is a patience, if you can not do that then you will lose, and if you take action to hold the coin up to several years to come it is a good action like investment.
Yes trading sucks sometimes, so hold your coins. And I would like to add some more things to do during crisis i.e. as follows:
1 Try to control your emotions during hardships.
2 Dont panic yourself when bear any loss.
3 Try to learn from your mistakes and make some wise decisions.
