For a long time there were no good and convenient projects with payment cards. I looked for such a system that would allow to quickly change fiat to cryptocurrency and withdraw fiat into cash. I hope the service will find how to cooperate with the largest payment systems to settle usage.
one of the successful projects that applies like that is MCO, AMON follows their lead, maybe AMON can be the second choice after MCO
but unfortunately AMON is still far below Qrypto.com (MCO)
