lol at the end I tried and lost 200USDT in less than 5 minutes, the chances of loss were 1%. Very suspicious at the first try...
Your loss is proof that even in gambling, even with a 99% chance of winning, you can still lose if you're unlucky. This applies to all games, not just roulette - but all games as well. Many people experience this in sports betting - one example is the Liverpool vs Burnley match. So your first experience can be a lesson for anyone that there is no guarantee of winning in gambling even though the probability of your winning at that time is very high.
