I still see many people being puzzled by BTC, saying it's a bubble, that it's going to crash, etc...
Taking advantage of the huge price rise, I think some early believers should team and buy an existing bank. Not Barclays, nor JP Morgan of course, but there are small banks out there. Imagine a bank owned by bitcoiners, for bitcoiners. It would become an exchange, and it would be the best exchange in the world with the full ability to make Swift and SEPA transfers without the need to use the service of a third party.
Why you just build an exchange instead of buying conventional bank? Rather than that if you bought a bank and you live in the country where bitcoin is still prohibited to be use as mean of payment or sending money it can be worthless. Also, there will be many people who will dissagree with that by the reason bitcoin is decentralized system which mean if you are trully bitcoiner especially holder bitcoin for long term investment you will not use an exchange or even a bank to store your bitcoin. Because you will choose cold wallet to store your bitcoin, it is more safe because just you to secure the bitcoin that you had.
There are disadvantages of setting up a centralized bank for crypto users.
Right now, that purpose is already catered by crypto-exchanges where you don't need to submit KYC if you fall below their daily max withdrawal limit.
Which, is really a big advantage for a lot of crypto users who don't want to divulge their identity.
And it is true, in crypto, it is better to store your coin in your own wallet not to any entity out there who will have the control of your coins.
In terms of SWIFT and SEPA transfers, a crypto user can just transfer his crypto from one country to another, and the receiver will be the responsible to convert it to fiat according to his local regulations.
