I would choose for a bitcoin wallet its more secured, faster and easier.
Also your not dependent on bank that controls your account.
Well I would say that an online Bitcoin wallet and a bank have the same amount of security. But Bitcoin wallets are just better.
If you are scammed with your bank account, the receiver has to return the money to you. For bitcoin account, there is no way.
thats why we should make escrow system in between both parties, It would help us to keep our bitcoin in safer side. find the most trusted people. instead of goes with scammers. and then even banking sector people faking many people by loan and interest and many things so all are same. main thing is how we are managing it.
