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.
And how exactly what this be different to any hosted bitcoin wallet or exchange?
It doesn't make sense for a bunch of decentralisation enthusiasts to be embracing the precise thing that they swore to replace in the first place. It definitely does not make sense to try and attempt to take over a bank and transform it into a non-efficient exchange when there are much more established alternatives (think Binance, Coinbase) that consumers will be more drawn toward for good reason or not.
It really offers no benefits apart from a short term, day-long boost in mainstream media interest and probably attracting a ton of critique from commentators. Not a great idea at all imho.
