One of the big advantages of blockchains is how we can cut out the sneaky bankers and can have a unheard amount of financial freedom. Getting involved in a blockcahin ran by the bank would surely just end in them some how controlling our purse strings once again. On the upside this should bring crypto currencies into the main stream more hopefully and convince the masses to hopefully get involved with blockchains more.

But they want to control everything, to control even the blockchain. So they are thinking about their own crypto currency - to have control on it. The next step will be smth like "all other crypto currencies are out of the law")
I hope I'm deeply mistaken!

Maybe this will get more people into crypto, but a government/big bank blockchain just sounds like a bad idea lol.

Never say never, bro
