Both are convenient. Why choose when both are available. Bitcoin for e-payments and my bank for other payments.
That should be good idea, because why we should choose while they are working great. To be honest we cant just use Bitcoin wallet only, we still need Bank.
Other's believes in those ancient beliefs and sayings about bank that's why they preferred bitcoin.
Other's doesn't experience yet in using bank.
Same with bitcoin. Other's preferred bank. Other's comfortable with bank.
That's why many has different answer here.
They are just looking in a single tree and not on the whole forest.
I know, but using them together isnt bad at all, before bitcoin getting mass adoption then we still need bank..
