Can I enter Binance generated BTC Address for deposit into Slushpool Payouts Wallet for long term use ?
Is this address fixed or changes from time to time and if it changes will the old address still be valid and I'll receive the money?
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).
No,it is not safe to store your bitcoins for longer term use in online wallets both coinbase and binnance are not safe so you can use blockchain.info wallet which is more safer than those wallets and in blockchain.info wallet the fee is less when compared to other wallet service providers.But for long term you can go with wallet which supports segwit address so your transaction will be faster and with less fee.Maybe you can choose Electrum but upgrade to the latest version because old versions have some vulnerability.
