I prefer the bank because it still stays a bit safer if you are asking me and it has a great future too due to that I think that the bitcoin wallet is also good but its not very good secured sometimes.
I agree with you . BANK more guarantees for the safety aspect. they already have the guarantor is a government institution.
bitcoin while still anonymouse so there is no institution that guarantees the existence of bitcoin.
Banks only guarantee your money till a certain amount which is different in each country, but everything you have above that amount will be gone for good if something happens with that specific banks.
Also, we don't need an institution that guarantees the existence of Bitcoin since miners already do it for us....
