so i wanna know from all the bitcoiners here is there a some kind of bank where i can deposit my bitcoins and get safe transactions and not worry about theft or lost of wallet ??
Bitcoin is all about "being your own bank" . Banks are far from being secure and safe anyway , they could get hacked while when you have bitcoins in your PC , It won't be that easy unless the hacker targets you personally . On banks case , everyone targets it (as It contains millions of dollars).
If you really want to stay safe and have much to store , I'd recommend buying a Trezor (Hardware wallet).
