It would be better if we have BTM  that we easily withdraw our money into cash. No more hassle on the transaction.

I don't think so, many bank nowadays accept cryptocurrency. Besides if you want to cash out your earnings you will get the money in the bank. Blockchain is a good way to communicate because aside of its privacy it is also used in transacking a money  without the approval of many. Bitcoin might close the banks but they could not stop it.

What about Belarusian banks? I read that Belarus want to legal BTC.  

There are banks that accept bitcoin and it's very good to hear because it's very reliable to some investors. Bank in my country accepts bitcoin now when withdrawing money, this is a good way to receive the profit you've put an effort.

Any bank accepts Bitcoini but accepts a few banks but agrees with a small number of banks, which is why Bitcoin is still not legalized in a few countries.

The bank is not yet a Bitcoin fan. JP Morgan is hostile to Bitcoin. Citibank is skeptical. Goldman is curious. But almost all large banks have brokerage offices, which are members of Bitcoin exchanges that are currently trading bitcoin futures. These futures contracts eventually brought Bitcoin to Wall Street. But it takes time for Bitcoin to win the trust of Wall Street brokers.

I don't really think so. There is a registry of database in every bank that tells them what kind of money and currency they can only accept, and I'm quite sure that bitcoin is not on that list. Perhaps the reason is bitcoin is just new to the world and the fact that bitcoin has no physical form matters as well. Banks have been using their own policy for a long time, so accepting something new is debatable.

We all know that all banks do not accept bitcoin. And there banks that shutdown some bitcoin related accounts.

I think there are no banks would like to accept bitcoin. Due to issues about crypto in the worlds and they won't accepted it until the government legalise and give policy about them.
