Martingale betting sucks. I thought OP is just having beginner's luck on this form of betting and got carried away.
I suggest OP just continue using that betting method and see the result in the long-term using it.
Even a $10,000 bankroll and you will start with lowest allowed minimum to bet can be depleted quickly using a martingale.
It works to some but to many, Martingale is not good and it can cost you a lot of money if you thing this strategy works. Theres no proven effective strategy in gambling, we all have our own techniques but still the house will always win. Most of the time Im gambling without thinking for any strategy, as long as it is still within my budget and I dont become greedy, having techniques is just an alternative for me. I prefer more to have fun than to focus on ineffective techniques, it can be more stressful if it fails.
