the wallet is from Binance and the key is over two years old. It is true that about two months ago my bitcoin wallet address changed.
I don’t see the point of the receiving address being KYC or not since you will only use it to receive the funds. Freebitco.in doesn’t care on what Bitcoin address you are using since it’s your own personal choice.
Your problem is due to Freebitco.in delayed processing your withdrawal since the transaction is not yet submitted on the Blockchain. There’s a lot of delay withdrawal before so your only choice now is to wait for them to process it. Again AML restrictions on your receiving wallet shouldn’t affect your withdrawal.
