They have great marketing on the forum, which isn't the same as having a great reputation.
Thank you for your comments. It's always good to be skeptical, but I'm not going to get into the technical debate between you and TheQuin, but a couple of points:
I've always wanted to know if they really pay $271.37 on average for 10000 rolls. And if so, why don't they just pay $0.027 for each roll?
Come on! I understand you live in Europe. Why does Euromillions have a €104M jackpot for the next draw, instead of distributing more money among the smaller jackpots?
Based on the odds, I would expect one $200 winner for every 2 $20 winners.
I did a (manual) count on pages 5, 10, 15, 20, 25, 30, 35, 40, 45, and 50 on
Big wins at FreeBitco.in:
I just won $20 at FreeBitco.in! 116 times
I just won $200 at FreeBitco.in! 2 times
I probably miscounted a bit, but let's round it down: winning $200 is 50 times less likely than winning $20, and that makes the difference
25 12.5 times larger than it should be.
The truth is that I find it hard to believe that you wrote this. It's obvious that not everyone has a bitcointalk account and not everyone who gets the prize is going to post in that thread.
I was playing in Freebitco.in during ~3 years. These are my achivements on the sceenshot below. Free rolls played = 10467. The biggest numbers I rolled are:
9993 - 1 time
9992 - 2 times
9990 - 1 time
9989 - 2 times
and never bigger than 9993.
Really? I don't get into the other more technical stuff you mention but that may be due to simple and pure variance. Are you seriously skeptical based on one person's statistical sample?
My results in freebitco.in are also below average, but as I have been playing poker regularly I am used to the fact that the most normal thing is to have results well above or below average.
See a graph of a winning player in poker tournaments. If he plays every day, he spends most of the year losing and can make a year's worth of profit in less than a month.
