The coolest crypto project that I found was a etna project
You mean etna.network? It doesn't have anything except wallet, and the team looks shaddy.
As a big fan of IDO's ^^ I'm currently waiting for SupraOracles IDO.
My problem with IDO and this SupraOracles is they don't have product/prototype, only promises, and that's not good.
I wish I had done the same and sold off. I got way too many bags now, most of them looking miserable.... Buying is easy, but selling I find difficult sometimes. Now I got more good coins I want to invest in, but already spent all my chips on all kinds of madness.
Well, that needs experience mate, I did the same mistake in 2017/2018. Low marketcap coins are generally for short time holding, once it profitable, sell it all. If not you'll become a bagholder for years.
