what are you talking about? Tournaments we are running is FREE for all! It's our promo. You can deposit 10k of tokens to get up on top-balance list. Play tournament, /win/lose/play against other players. In any moment you can to withdraw you tokens and sell.
P.s
If someone put in 1500 ROUND and then only got 400 ROUND because of the "equal" refund then that means 900 ROUND were lost from that user at the hands of the devs.
In total you will have 1900 tokens. But i think you already know it.
No, check your math dev. 1500-x=400. What is x and where did it go? It was unjustly distributed to others. This is textbook fraud.
