But we don't know his story yet why he bet that amount of money. But even you bet small money possible all your capital will gone if you do not know how to handle it.
The story why he bet $1.5k 2 times because he wants to recover $800 his losses before (it already stated on the title). With $1.5 bet on 70% win chance it means he took around $450 from each of winning bet.
If he ended the game after that 2 consecutive wins then he got something from his gambling activity, getting $100 is much better than losing your bankroll, that aggressiveness will only lead your stay losing everything though sometimes lucks permits things to happen and allow gamblers to win if he can manage to quit and be contented with what he got.
Not all would really be contented on what they got or recover up their loses plus having some small profits when a green bet hits up.If luck permits things then stopping along the way will already be the issue.Gambling on this way isnt already enjoying but rather a stressful thing for you to think about.
Worrying,thrill is there when you do know that you are risking your entire bankroll.
