I do bet but not often. I am not the kind of person that place a big bet on anything. I am afraid of losing but seeing people on the list with corresponding amount of winning is quite surprising for me. I can't believe that it is possible to earn that kind of amount through betting only. Maybe they win often than lose.
I.also don't bet big amounts, that is not for me. No matter how good odds might look I don't take big risks.
It's possible to make big money with betting, there are also some examples that I know but for that you need to play big and also lose big. It's not possible to win all the time and at the end the question is how ratio between won and lost actually looks like.
I have seen people winning 100-200 odds live in front of my screen so I cannot even say these are just fake and made to lure the players into gambling with high odds.
The best chance you ever have of hitting high multipliers is actually on sports bet parlays.
Yes, betting on parlay gives you a little chance of winning only, but as you see there are people who really win, then I guess that tells it's not impossible to win and maybe your luck will come at the right moment. Risking what you can afford only is advisable, it doesn't matter how much as you can even bet less than a dollar because most crypto sportsbook allows that.
I just put a bet of 0.5 mbtc on a parlay bet on sports in my sportsbook and they accept it, that's half a dollar price.
