Well, there is one big problem with your logic train...

the train track is about to be removed.

i do not believe The US dollar will be in existence in 2030.
But, before that, there will be a lot of Hive millionaires just because of hyperinflation.
Although i don't know what a million dollars will purchase.

Also, that is a lot of onboarding that is going to need to be done.
We need a lot more users to get to a million, and even more to get a million to a million.
