18 billion --> 618 billion = ~34x
2018
618 billion x 34x = ~21 trillion
Can't happen the growth is too high, despite that though we can still have good gains this year.
This is a good post. I did some checking and for it to reach $21 Trillion, it would be in the ball park of the US stock market ($30T), bond market ($40T), and real estate market ($25T) ...
Crypto is a new and hot asset class, for sure, but I can't see it being on par with those behemoths for a long while.
