As long as we’re not lazy, we can do this. Start with a small amount if you’re not fully confident in your sports betting skills yet. Most crypto sportsbooks have a minimum bet of around $1, so even with a $100 bankroll and a 1% stake per bet, you’re off to a solid start. Then, after the whole season, whatever league you’re betting on, take some time to evaluate your performance and see if you’re profitable or not. If not, make the right adjustments and try again in the next season, and keep going until you find success. Like I said, just don’t be lazy, and stay focused on your goal of becoming a profitable sports bettor.
I would emphasize this "as long as we are not lazy". That's usually the biggest problem, getting ourselves to move and do something. Another big problem is consistency, once we start we have to repeat it every time we bet... I tried several times and every time I stopped after a week or two. Usually what happens is that I postpone it once, then one more time, and then just leave it. The third problem is patience! I have no patience for long-term sports betting... I easily decide to play slots or some other games, then my balance goes up or down. I have never had a balance just for sports betting.
So, it's actually a good thing to track bets with a spreadsheet, but not everyone can do it... at least it's hard for me. I will probably give it a try in the future again but for now, I will simply enjoy betting without tracking my bets.
