made a withdrawal from Octafx and tried to transfer amount to my bitcoin wallet.tried my bank account and was advised that this option not provided to south africa and all attempts where rejected Octafx gave me option to withdraw using Tether ERC20 or TrC20 which I choose ERC20 and linked my etherium wallet adress from my luno and withdrawal was successful only to find out the network used was burned in south africa which is USDT in this case money left dangling on the network and lost.
