Never tried lottery game using a coin. Most of the old exchanges has a lottery game and I tried my best to resist the temptation on playing but for some reason I tried to click the dice multiple times and lost $50 in 3 minutes. Gambling has its own way for players to keep on playing. NEVER try to play the lottery on exchanges . It is a game that nobody wins. They just take away your money feeling that you've been scammed LEGALLY.
