MY last big win was $800 in last month. and i won it from dice . i was roll for $400 and set profit 2% and win/loss 50/50. I lost all my money here and re-deposited the remaining $400 there and I angrily bet all my remaining dollars there. But then my luck was good so I won and make my money 2x in 1 min
You were very lucky then to have won up to $800 in just one bet, I have been trying my luck in football predictions but luck have not been on my side to win such a big amount, the last I won was around $50 and that was a long time ago. For now, I may choose to stay away from football prediction and start playing real gambling games to see if I can win because of my basic skill in some games and I am expecting to win.
In sports betting you have to use big money if you want to get big wins too unless you like betting on parlays with small funds if all the matches go as predicted it will give a nice win, but it doesn't always go well even the percentage loses more than win when betting parlay.
