You ask such funny questions because each site has its own rules. In many bookmakers, my minimum deposit, for example, on W88, I could bet both the minimum amount of money, which is about 10 pounds or 12 dollars and the maximum, which has no limit. And now I've won 5 times in a row, and so far, I'm lucky. Still, I think I should finish it sooner or later, because as you can and quickly win a significant amount of money, so you can lose it, so as soon as I win another bet, I'll withdraw money to my account. And yes, you should formulate the questions a little differently.
I also try to stop in time when I start betting or playing online casinos. Especially if I get a big win, I feel that I can lose it as quickly as I won. So I decided to finish the game and don't let my excitement take over me. I play very carefully, trying to keep myself in check. That way, I can play a few hours before my paycheck ends. And I'm lucky that nowadays there are online casinos like https://12betno1.com/, where there are good odds and a chance to catch luck while playing.
