I guess we are talking here about Ponzi shame with sale restrictions. Simply example - if you bought at 10$ you are not allowed to sell lower than 15$. Such asset cant go down. It just can stop grow and left people will unsalable bags - effectively worth 0 but on chart worth xx$.
Owww... in this light it all makes more sense.
Well, a Ponzi is a scam, no matter how it's wrapped and how it's called. And I was expecting a proper legit business...
And yeah, such rules, while ensure the coin is (one paper) never falling, it also makes it just another scam.
