Hmm i really dont know banks that is bitcoin friendly or banks that let you do transaction under them using bitcoins.But here in philippines we can cashout our bitcoin and convert it instantly from (PHP) which is our local currency here.We can cashout in each bank that is listed thats more likely 5 banks.
Actually it is because Coins.ph can have an account that can send money to those certain banks. One is Security Bank which is for Electronic transaction but still I doubt if those banks "do know" that it is from bitcoin they are dealing with. It is just that Security bank is giving us an account and a password which is from their own.
So still it is Coins.ph that is like buying bitcoin from us in a cheaper way when we exchange it to fiat. But still good observation my friend.
