And I am pretty sure I won most of these bets, so yeah - All In betting could be fun and profitable in the same time.
That is good. Cause you bet when you are leading well so you are actually max the use of your money to work out the best probability of winning.
I don't think that all in is profitable, all in gambling depend on risk and luck, when you use you all amount in gambling, no one give you guaranty that you will win. but in the other wile, if you use the gambling fun and game than all in betting never disturb you if you win or loss.
His posts doesn't make any sense. What kind of assurances can you have that you will win? Unless you are a hacker or cheater, there are no guarantees. And cheating or hacking is not considered gambling because you know the outcome.
