On the one hand, the project looks like a certain type of gambling, which is not very good and fair, but at the same time, players do not lose anything.
In what sense do players lose nothing if a person participates in a draw and does not win anything - he does not lose the amount that he invested in the purchase of a ticket?
But in this case, the tickets are platform tokens, buying tokens you even after the end of the lottery can sell them again or again participate (if I understand correctly)
