My search about this news did not bring any quality information why FSC want to ban the company from receiving deposits and withdrawals in crypto but they said if customer have any question or needs help they can contact them directly.
Crypto withdrawals will soon become unavailable. Exchanging crypto for traditional currencies and vice versa is also going away. If clients have funds in crypto accounts/wallets at FXChoice, the company strongly recommends that they withdraw them before 26 December. Clients can sign in to my.myfxchoice.com, check the balance on all Live accounts and Wallets, and go to Withdrawal to claim their funds.
Starting 12 December, FXChoice will not be accepting any new crypto deposits.
If you have questions or need help, FXChoice encourages you to contact the company using any of the channels via its site, including live chat, email or its ticketing system.
