I don't know what more to say about your pyramid argument. A lot of folks have already tried to explain this. All PoS coins would be a pyramid scheme by your reasoning. And they are not.

Looks like TC11 is your inviter as per https://merit.disifi.com/wallet/Maicol792. He's available mostly on Discord. You can connect to him there to get your wallet unlocked. If he is unreachable or your wallet still remains locked, you can use my link (in my signature) to set up a new wallet with the same alias (all aliases are up for grabs until they get unlocked). I'll unlock your invite request.
