For me it’s good strategy , but its pretty slow way to earn. And there is a risk to get 15 time low bet in row. Maybe if I had bigger balance maybe I will be still in game. I saw once that my bet was 600 000 satoshi, then I won and started again from 5 satoshi.
I don’t recommended to use my strategy if you put your own money in that site. I was gambling with balance that I got from free roll.
At the end Freebitco.in will take it back all

I would say that as long as the house edge is not on your favor, you are going to always end up losing. I understand that you have shared a strategy and I can bet you a billion dollars that you can't keep making money like this forever, eventually if you keep it going then you are going to end up losing. That "15 in a row loss" is not impossible when you look at it from the longer term. It is going to be something normal and shouldn't be all that weird.
I understand that we are going to end up with a situation where it will not be impossible to get it changed on the long run. I get that some people may end up with a win here and there for a while, but if you bet 100k times, having 15 in a row loss is not impossible and you are going to end up with it %100 guaranteed. That's why all strategies lead to same thing; a loss.
