Generally, it remains valid (even If it changes, you can still use it unless they state otherwise) as

Yep I have seen it before asking. I just want feedback from miners to see if it is ok to use binance BTC address on Slushpool or it's better to use other account like coinbase and than transfer to binnance. I just want to save on transfer time and fees (Network Transaction Fees).
