I think crypto has no real value as such, no bricks and mortar to it and as of yet, I have never heard of a crypto millionaire cashing in their coin and becoming a "real" millionaire. The banks will still be interested and dabble but so far non of the big ones have touched it in any major way it's seen as being way to volatile and for the most part very dodgy, to say the least, and most shareholders who are usually very conservativ probably wouldn't support it.
As I posted earlier,
"I looked over a crypto banking machine at my local shopping center next to the NAB, Com Bank, and StGeorge machines, you could make deposits ok but not withdrawals...
I have been investing etc for most of my life and I see cryptocurrency as just a get-rich-quick gimmick for smarty pants millennials to lose their money with.
Call me an investment dinosaur and an old fart but so far I never heard of a crypto millionaire becoming a real millionaire so putting it simply, unless you can get your money out as quick as you can put it in I'd give it a big miss."
(But what do I know)
