After the crash of ZEC... I don't think this coin will do something... and with all those new scam clones of ZEC (ZCL, ZDASH,...) it won't help either.
I hope people can ask for a refunds

Are you talking about one of those coins you mentioned or Komodo? Sorry but, most of us disagree with you and we have put our BTC on the line to prove it. And, ZEC didn't crash, it is simple reaching its true value. KMD tech is miles ahead of ZEC already.
