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.
You are absolutely right, in all my years of being in crypto, and as well have been participating in a lot of online gambling casinos for a few years now, I've never come across any online casino where users are required to kyc their crypto receiving address, doesn't matter whether be bitcoin or what ever, if any platform will ever come up with such kyc policy, then that will definitely go down as an extreme fight against users privacy.
What I believe we owe casinos and other kyc complaint platform is to provide our personal information with which we can be identified with the government of the country where we live, not provide information that grants the platform access to monitor our entire online activities and transactions even ones that have no business with government.
What I supposed caused the delay in processing that withdrawal request is possibly due to the high fees on the bitcoin blockchain, may freebitco was waiting to see if the fees will calm down a bit at the time the withdrawal request was placed.
