Highly advise everyone to stay away from this site. If you lose you lose 100% of your bet, if you win you only get 10-30% of what you bet. The house rake is absolutely insane and you are going to lose money
Most smart users with a strategy win a majority of the time. I have seen users that have never lost.
There are no predetermined odds. You have the ability to wait as long as you want and obtain real world information. 10% Payouts are extremely generous for those pairs that are predictible. 30% payouts are more risky but higher reward.
Coming with a strategy can help you ensure winning a majority of the time.
