I only use 1 .and thinking of having anogher 1. maybe they plan there first to be there savings wallet. the othe the investment wallet and the others for gaming or trading. i just think so
i use only one bitcoin wallet too, i just dont need any more right now to be honest and i hope that i wont need it in the future too because it would be hard to find everything
in my opinion people should have two different bitcoin wallet, why? the one for large amount transaction with very high security and the other for your daily uses with normal security , it wouldn't be good if everytime you send the coin from one bitcoin wallet it's shown how many you have bitcoin and people could trace the owner and doing something bad.
Those users having multiple bitcoin wallet mostly they are gambler because some bitcoin wallet will get you banned if you received income from grambling, and also they want the services each bitcoin wallet.
