Earlier quoted context omitted.
The explanation is simply that there are people that have bought in that want others to buy in also so they can liquidate for a profit. Meanwhile, others are susceptible to what amounts to FOMO-driven investment. The same sentiment that drove the beanie-baby craze, the dot-com boom, the subprime mortgage crisis, the current metaverse craze, and so on. Nothing new under the sun.
>there are people that have bought in that want others to buy in also so they can liquidate for a profit. Is that any different than a ponzi/pyramid scheme?
Crypo cannot create or destroy fiat currency. So if you sell your crypto and make a profit in dollars, it's exactly because someone else bought it at a higher price than you did.
And they expect someone else will buy it from them, in just the same way...
So every dollar that comes out of cryptocurrency is because a later investor put a dollar in.
Doesn't that sound like the definition of a Ponzi scheme?
