Is it possible to withdraw bitcoins to bank account
Certainly it's impossible. What you need to do is to convert it into a fiat money through coinbase for dollar, coin.ph if you are from Philippines. If you can't do both of that, you can convert fiat money directly to a person who trade btc-fiat money pairs vice versa
.
I have checked in Google about the bank accepting bitcoin. Unfortunately, no proper results about it. Could you please pass the link to here. Even in my city, I do not able to find any banks that accepting bitcoins. If the bank accepts also its waste according to me due to penalties and maintenance charge all will be applicable then.
