There are allot of people who get scammed with that stupid bitcoin wallet so in my opinion it is not save enough to use the bitcoin wallet right now so for now im just using my bank account to mannage my money/.
It is their fault on how they are scammed from their bitcoin wallet, Bitcoin wallet sites are protected and secured it is your duty to keep your bitcoin wallet information private. Then, why are you here in bitcoin forum?
But it is still better to use both.
