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 ??
Once you saved bitcoin it's on your own how will you make it safe.
If you use web wallets as storage then it's prone to fraud activity. Even storing it in a cold wallet or desktop wallet is not an assurance that your coins will not be lost.
Bitcoin is money so treat the security of bitcoin just like on fiat. About your question, no it doesn't have a bank but rather exchanges.
