Honestly I am a soccer and football fan. So I can say that I am interested to join and experienced this kind of betting game here in crypto. But honestly I am also afraid to loss or become a victim of scam. All we see the amount of betting flow it is really serious amount. I will study this game first even I have save some eth to my wallet.
it is only scam when you are asked to pay for the games
I , personally , check the bets out and use my own brains - some of the bets provided are already in my sights , some make me run the math on them and see if it is a good value
but never rush and bet blindly based on the tipsters' bets , you risk to get your bank zeroed when he goes on a losing streak
you can bet flat amounts , for example, if OP gives 10 games , divide the total amount you can afford to lo ... bet by ten and bet 10% of the bank per game
I highly doubt 75% of wins on a 1.8x is possible in the long run , but if OP proves it during 3-4 months , I'd say pay close attention to his tips
