Cashout when the value is negative

Hi guys. Just a question. Sometimes you place a bet with a good value (lets say 5%), but after. a couple of hours, you check the odds on asian bookies like Pinnacle and realize that the odd loss value (1.85 in Bet365/ 1.83 Pinnacle so a difference of 0.02 not value if you ask me). So what do you do in that situation? Do you cash out? Or keep the bet jus in case.

I used to cancel the bet, but somehow those bets were won… I don’t know, maybe I need to have faith.

Also, I just won a 100$ Bonus, and my friend ask me to win his bonus. Do I need to hide my Ip??
