I completely disagree. We don't need "big" FIAT money to come into the space to make it grow.

The view that more "big" money comes into the space the more it grows comes from only viewing the space as its FIAT/Crypto exchange pricing (i.e. USD/BTC etc...)
We need to be judging the space by:

the size and use cases of utility tokens
the amount of transaction growth on each blockchain
how many unbanked people in the world now have access to financial services

We need to stop discussing everything from the viewpoint of an American day trader.
