I have all these coins in holding until ETH turned 4000$ weeks back and I instantly let go of them all, now I'm buying back little by little taking the advantage of every dips, all I can say is these coins will go way down very soon and that will be good time to start picking them up one by one
Yes, make the investment with a certain time interval as the prices change. Secondly, be careful with the projects you choose, as we do not know how the situation will continue. Check less risky projects such as top projects because the new ones are weaker and they will make you lose more in the bloody days. Finally, I recommend choose top coins those survived in the bad days and still lives.
