There's a new zero fee exchange called Cobinhood(https://cobinhood.com) that support fiat.
It's relatively new and is actively accepting new coins. Maybe the devs would be interested in contacting them.
@robert-bocanet your money shouldn't be lost. You just need to make sure, that your wallet is synced with the blockchain. Blockchain includes every transaction ever made so also yours. Which means, once it is synced up, your balance should be corrected.
@zeljko-stanojkovski I know you guys are working on it - I just want to let you know that I post my tracks and talk about Musicoin on Facebook groups and hear complaints that the site is slow and people are having trouble signing up. It's good that there is lots of traffic! Happy to be participating in this project - don't rest! Keep it up!!
