For staking I think its not so much reward for bnb and ada.  But if there are launchpads on binance,  then youll be earning more from it provided that you are having a lot of bnb.  Its kinda low pool on their exchange for bnb and even ada so youll need to find a decentralized which giving a good reward.  Not surr for ada since I am noy fond of usimg their network.  But if for bnb,  pancakeswap have variety of pools or farming.
