Yeah cognitive bias is a bitch when it comes to gambling. Never bet on sports you are not knowledgable about in any way.
Don't involve unknown fighters in your main stakes. Bet on big favs and small dogs. young guys usually start as a small dog vs a veteran, but if they bring an 8-1 KO record its a good choice. Just bet smart, think about your picks. run multiple on your smart /safe accumulators and cash one out when you can. This will also stop you from degen spamming.
Set a stop loss and don't hesitate to give yourself a cool-down on a site. When your head says you should, DO IT. Because you can clear out your account because of tilt so fast, just to tell yourself how unlucky you are etc can never win.
Or if you won a few times pretty big, you don't add up all those losses..... SO USE SPREADSHEETS they are a slap in the face and will tell you where you are losing a lot of money. Usually it's all those little ones that add up, and the ones you feel confident with would net you a profit.
But yeah who would not stake 1 to win 100.000 or 10.000 or 100 even if you are in that mood.
I used to play a lot of online poker and while I was a consistent winner in cashgames, I never liked the grind, so I always played tournaments of 8+ hours, multiple tables with top heavy payouts. and if I won big I took a big shot at the cashgames, or if I lost some weeks in a row, i would just tilt off.
Tilting can be OK in poker because i would just launch a bunch of 0.10c tournaments and go allin every hand. With sportsbetting I don't know.. didn't have it yet. But stay away from those Blackjack or roulette buttons
