I think its hilarious that you came in AFTER the biggest hype cycle, claim to sell at the top and buy and the bottom and think people should listen to you.
I have been in it since 2013, and yeah, it cycles, like every single asset from a farmers market apple to gold and oil. Difference being, bitcoin ability to transfer is lightning speed compared.
As for ponzi… you either don’t know what a ponzi scheme is (hint: it not the same thing as greater fool theory, which is what you are describing) or your line about diving in the space is utterly untrue.
I suspect the latter. You sound like every cryptobro who places value only on the dollar conversion of bitcoin. Boring.
