even if you know a lot you'll lose hard at some point. no matter how much knowledge you have regarding sports, it is and will always be gambling.
I think the key is to not bet everything on one bet. Then for sure it is ensured that you will lose everything in the first bet already or at least in one of the following ones.
Though if you bet only one tenth of your value for each bet and you really have an advantage by knowledge then it is harder to lose everything. Though one tenth would mean you would have to have a big advantage already. If you have only an advantage of 5% then this would mean the chance is high that 9 bets, it's still gambling, can lose. You would end up with one tenth to one 5th of your investment. And it would be hard to crawl back from there.
But with proper caution and an advantage you will have the chance.
That correct, it is like investing. One must diversify investment similarly one must bet on many games with small amount to reduce risks.
Betting on many? Isnt that more money to gamble and might be more to lose. I dont know man. It is like more scarier than betting on one.
