Sorry, i don't understand what you mean. I don't Charge doubble! I Charge 5% (0.005 btc) of every 0,1 btc Bet. Everything Else remains in the game and is Used to cover payouts. It would Be Great if the Bank would have more money, but its running 3-4 Weeks now and there is no noteable increase of the banks balance. At the Moment it decreases. Or did i missunderstand you?

Sorry for upper/lowercase, i am typing on the mobile.

What I am saying is that the money "in the Bank" is your money as well. Your profit, or more exactly your expected profit remains the same and is above 5%.

So tell me what you would like to change and how the bank balance could be increased to cover more and higher bets?

5% seems more than fair to me, does it even cover your costs?

It's a company server, I have no direct costs for the server. It will be running anyway.

I think so, the complete all-played-games-percentage is 47,68 % at the moment. I checked the connection to random.org, but there are no problems.

I checked the database and saw you played 80 rounds. At 50% you should have won 40 games, but at the moment you won 34. You have to win just 6 games more to be even, I think thats in normal range.

It would be nice if we could see the personal total bets... Smiley
I've bet all my (4.6~ BTC) on your game, lost all in the end, and I think I've won 44% of the bets.
I'm mildly unlucky? Yeah. With the 160% and very difficulty JP, It's a secure loss for me Sad
0,2% chance of win JP.
my 184 bet = 36% chance of won...

Does anyone have contact info for this site? I think it ate 0.2 of my bitcoins and I'd like to get it sorted out. I couldn't find anything in english on the site for how to get a hold of the operators.

"Da Man" has apparently not been active on the forums since last year.

Betcoin.eu ist mit most likely fraud.

I just conducted 112 games with a bet of 0.1 BTC each. I won 41 games. The likelihood, that the true win rate equals 50% is just 0,6%!

The calculation from my statistics tool:

Exact binomial test

data:  41 and 112
number of successes = 41, number of trials = 112, p-value = 0.00589
alternative hypothesis: true probability of success is not equal to 0.5
95 percent confidence interval:
 0.2770590 0.4623553
sample estimates:
probability of success  0.3660714

In plain english: The likelihood to win just 41 times out of 112 tries with a postulated win rate of 50% is just 0.00589 or 0,6%! By 99.4% the true likelihood is something completely different. I only observed a win rate of 37% instead of 50% with a very significant sample count.

-> Stay away, the indication of fraud is very strong in my opinion.

Figures that three days AFTER I found the site, it was added to the "Fraud/Unattended" category in mem's list.

r4in - look at his comments that mem made on June 23 in his gambling list thread.

I was playing on June 20th and the jackpot was at 35 bitcoins, which I calculated would mean ~154% expectation for BTC0.1 bets. I was actually considering playing until hitting the jackpot and sent three separate BTC0.1 bets in one transaction to make sure it could handle it the way Satoshi Dice can. Only one of the bets got booked the site kept the rest. Looks like that little amount may have saved me quite a bit of money.

Mem suspects there is a bot that checks the random number ahead of time and places the bet right when it needs to.

F that site.

BTW - the way I calculated expectation was 2/5 x 1.6 + 49/500 x 2 + 1/500 x 350 = 153.6%

1 betting unit was 0.1 and the jackpot was ~35BTC so, 350 units in the last one there.

Does that calculation look about right to you?

Even now with the jackpot at only BTC13.9 the expectation should be 111%. I suspect that mem's theory of a bot playing and keeping the jackpot has merit.

mem here again,

yep - the numbers can be pre-checked and the site op can easily insert a bet at the right time.

I saw a player(bot) wake up from a 16 hour sleep to place a single bet after I had a string of 10 losses.
The play did not come back online until another 10 hours later.

I have also had non payout issues and bets simply not being placed.

Unless the fairness issue is addressed I will not be shifting out of the scam list.

Hopefully I can sit down tonight and update my list, still catching up on all the backlog + I have started a new perl project on the side.
