The biggest enemies of the cryptomarket are the peoples greed of the cryptomarket itself.
Lots of the cons which were introduced from mid 2017 are just useless but combine this with the Fomo and greed of people and you have a winner.
I’m not going to claim that will not happen to m, but I did read the whitepapers of 80% of the coins I do have in my portfolio! Still will one of these could vaporize but at least I know how to blame, namely myself.
I’m did jump on he cryptos end 2017, so my port is in deep red figures. But I can keep the faith, cause I know the use cases of my coins and do follow them.
