In Russia, it is called "Pyramid". We had such a person, Mavrodi was called. Read about his "MMM". In fact, the rest are only plagiarists. But he was not the first, he just could throw the whole country. As a game developer, I don’t care about dragvars, since they are not competitors. Yes, I plan in the future to release the game for "steemit". PS I am writing from a friend’s account in order not to give out my identity in advance. Without a finished project.
