I don't know what edge martingale gives? That thing danger in my experience, can wipe up your bankroll if luck ain't on your side and this unlucky day surely comes where no matter how long you play, you just ain't having a winning bet.
I meant it gives you more chances to profit from winning, but you have big gambling fund. Theoretically if you gamble with small bets chances of profit are big, but with bets doubling with every loss they can rise up pretty quickly. That way I lost almost all BTC portfolio when I had dice game on autobet after loss spree of more then 10 losses.
The edge is a rule on the casino and not o the betting method, if a game has a house edge of 1% thats a constante and will not change.
With martingale we have the same chance to win than placing a single bet. And with martingale we can lose all too if a win doesn't come in the next rolls
I expressed myself wrong, I did not mean edge but higher chances for profit. Thanks for explanation.
As for Martingale I used it but I would not recommend it to anyone as the bets rise sharply after losing a few times in a row. I was thinking I was clever when I started to use it, after some time grew confidence and even started to autobet (I usually gamble manually). As I said above it costed me most of my BTC funds when I came across loss spree.
