How come you still don't understand the situation? Local crypto exchanges don't allow us to send money to anonymous wallets. We need to register with a global exchange and transfer money from the local exchange to the global exchange. This requires a 72-hour waiting period.
Is that really necessary? From my experience with turkish customers so far and AML procedures for crypto in general, you can still withdraw to your own personal wallets and you simply need to declare who's owner of that wallet. The common problem I see is that people are using exchanges as their only wallet provider and that was never the right way to use crypto. Exchanges should be treated as exchanges ONLY. After buying crypto you should always withdraw to your personal, real wallet with a private key you control e.g. Electrum, Electrum-LTC, MetaMask, etc. Analogy to regular cash is that you should treat exchange as an ATM, you take money from ATM to put it in your wallet and you pay in a shop using cash from said wallet.
If you add an alternative payment method now, you will gain many more customers.
I would gladly expand but there are no real existing alternatives from your region except resellers. Maybe one day a new reseller will show up but right now the trend is that customers just buy directly via existing options.
