I only see those few are millionaires. Millennial doesn't really spend a lot of time on bitcoin and other digital currencies.
They care more about freelance jobs like graphic design, coding, marketing, photography, writing content or doing youtube!
That's what they care about. As for the bitcoin sector, there are still more previous generations investing here than Millenials.
Im one of the millenial, I think the reason why most of the youth out there doesnt have any interest in bitcoin and other cryptocurrency because they didnt know the different investment types that they actually do so that they will have money when they retire soon. They focus on easy money that they think like vlogging, but Im not against with that.
