Hi @ES1189,
When you stake, you stake your total wallet balance.
When you get yourself a HW wallet, a new wallet will be added to yoroi. this wallet will initially hold no ada. So first thing you do is to send your ada from your non-hw wallet to your new hw-wallet.
Then you delegate your ada in your new hw wallet.
Now your total hw-wallet balance is delegated. Doesnt matter if you deposit your withdraw from this wallet. your delegated amount will just adjust automatically.
By the way you don’t HAVE to move your ada to a new hardware wallet, but it is more secure.
