I'm not really trading much as probably others do but if I can suggest you something: don't panic-sell and don't invest in those "shitcoins"
To find which is the shit coin to do trade is a strategy. To find this, we need experience and have knowledge on trading especially you must know how to check which is a good coin to invest and which is a shit coin not to invest. Your suggestion is good but to follow this suggestion we need experience.
