Every one of those exchanges on original post list have bad reviews, they aren't good for IEO projects either, better to stay away from any IEO projects that use those exchanges like p2pb2b or vindax and others to raise fund because they will never raise soft cap through the Exchanges
I have p2pb2b account and almost more than 1 month not log in. I trying log in yesterday but i just shocked my accound suspended without event the right reason. And i just left then.
