As we know, not many exchanges will support the international wire transfer, what is the mainly reason in it?
You’re confusing some people, according to your headline the question was if the bank will gladly support Bitcoin, now you’re asking why many exchanges does not support wire transfer (if not all).
Well, when it comes to bank supporting cryptocurrency, I don’t really know if that is possible in anyway cause they both have difference. Bitcoin is just an asset and it’s not something that is being held in bank, you can only get it from the right source – Blockchain. So bank can’t support Bitcoin, but they can support exchangers that are into Bitcoin, cause every money you use to buy Bitcoin is being sent to the exchangers bank account.
For the next question on why most exchanges does not accept wire transfers, well, why would they accept wire transfer anyway? This is a business that has to do with online and you will have to do withdraw to the right source first, which is your wallet, before talking about taking it to banks.
