I think it needs to become easier to get money into crypto, when I first started it took 2 months before coinbase accepted me, which is crazy!
I think with new platforms like Bitfineon (by ALQO) coming that will be an exchange but with fiat pairs and the ability to make deposits directly on the exchange and as I understand it easy signups.
That will change the game, obviously not just one project will change it but when several projects like that finish what they are building mass adoption will be easier.
