Okay so, i have only been buying on the dnm since jan of this year and i started off not tumbling my coins like i would just do Paxful > AB and Coinbase > AB and nothing has happened... should i start tumbling anyways? however i think the reason why my circle account got shut down was because i didnt tumble....
This is almost certainly why your Circle account was closed.
Tumble your coin. Why even risk it?
