It wwll depend on the game you are playing , is this a slot? sports? or the color game?
If this is a color game with 3 dice and 6 colors to choose then i will do x2 bets everytime I lose and go back to original once i win.
Sometimes i double my bet also when i hit a big win, before go down on the bet. different game different attack.
What i have to say concerning this is that it all falls back to the gambler and their preference of games for gambling, some folks would love to extend their bet according to the amount they win, their are some who choose to double up to try their luck and make up for previous lose while some choose to stick with same amount even whether they lose or not. Well every gambler have their choice but regardless of whatever their choice is, increase in bet should still be done with a figure that a gambler can afford to lose. Left for me I decide to extend my bet on sports betting when I'm chasing big wins or betting on single games with bigger odds and lower when betting on a random game booked by someone else and I'm not quite confident on it.
