That might be the reason you lost 250k over the last 20 years, you bet higher when you are in a winning streak and gets excited, then you bust.
I don't know if there are mega luck periods that all you get is a win or not, but better don't plan your actions based in such premise, because the luck time may end in any second
I do the opposite. I chase after a lose and bet higher when I'm losing to get it back. When I'm winning I try play it safe bit keep telling myself to just make a little bit more and I'll withdraw now now. But now now never comes and I lose all.
haha, thats greediness, if you'll look at it, in general, we can say that it is like martingale, even you are not doubling it, but the fact that you want to recvoer your money, in the next bet, makes it a martingale of just another level.
