IMO, I think most of the cryptocurrencies are also working that way, do you mean that most of them are Ponzi too? is that what you are portraying mate? I believe it's not like that and it's not appropriate to say that it was an inside job, the so-called whales have money to gamble and take the risks thats why they also have a big chance to earn big profits out of it. and that's not a Ponzi scheme as far as I know.
