Are the coins hacked/cracked?
No, there is not coin hack, only with winning
did you make a bot to win the matches or did u manually play every game?
I am playing maually. I played more and now i am selling all my coins very cheap.
That's very hard to believe, as for it would have taken you hundreds of hours to start from the very beginning, earning 15 million coins does not happen overnight.

No, if you have enough coins you can play big and collect. There is 2,5m table.
yes it is true, I played on the table 2.5m in one day I can get 20m, then I lost again all. so quickly winning and losing.
nothing is impossible, I believe this because I have experienced
