I just use the online wallet, the reason is because it is simple, easy and can I access everywhere. I know that the wallet is offline is very safe, but because I'm still new and still small balance is of course currently online wallet is enough.
That is good for a newbie, you can stick to online wallet because you are just slowly learning how bitcoin works and what are the basics. Online wallet is one of the best and common wallet that most of the members here used because it is accessible anywhere and you just need internet to receive and transfer bitcoin but you need to remember that online wallets are not safe because of the hackers and it is best to turn on 2FA for additional layer of security.
