yes I know that, but on the first page the prize is '' cash '' which means it is money that can be disbursed not as a capital for trading. It may only need to be changed '' cash 'to NDB.
It is cash to your trading account. From my end, real money is being sent to your account. It is not imaginary money. So from my end, it is the same as sending cash. The problem is that the broker has certain rules, which I have no control of. If the broker did not have rules, the term 'Cash' would be no problem.
Even when Bitcoin was sent directly to member's Bitcoin wallets, this technically is not 'cash' too. It is Bitcoin, but the 'Cash' term was still there.
