Well, I'm glad I tried and I even more glad that I saw that amazing winning streak. 19 greens in row on 49.50% win chance is not something you can see often.
With 49.50% chance i do even rarely get that 9-10+x and yes 19 greens straight is pretty rare and its good to see that it is indeed possible.
140M milestone in a short span of time does signify that they are doing great.
2x or 49.5% chance can give you up to 26 greens ( or reds )
I've heard stories about 27-28 reds in a row , even posted here at bitcointalk , got to look for the topic , cannot find it now
but the max streak I got was 25 reds , I think and 23 greens
somehow green streaks do appear to be more rare for some reason
in general , players tend to see trends and streaks and then I hear something like : wow , I just got 100!! reds in a row! how is that possible? scam etc.
and when you ask the guy about the multiplier , he says 20x
