110 % ? Why should anyone play for 110% payout @ 50/50 odds ? I mean its 90% house edge mate I am not sure what your idea is or am I understanding this in a wrong way ?

Is this just for testing the site ? Will it be made 200% when site is active ? Let us know and good luck .

If you bet 10 you win 11. So if your initial balance is 10 your final balace will be 21.

Cool so its actually 2.1 x right ? So how will the site make profits ?  Its +EV and on short or long run user will be on profits . Eventually the Bankroll of your site will vanish , don't you think ?

I have a problem when i want to sign up there, register form is not clear when i want to fill my email, username and password, its make me confused ??? (even log in form)

Can you explain further which is your issue?

In the signup folder the first field is Name, second one is email, third is password.

No email confirmation needed, so just signup and login :) (remember to check captcha too)

Ah i see, maybe my java should be update, because the form name is not show. i also use other site to fill register form too and not showing a form name.
keep it work, i will try ASAP :)

Seems scammy.

110% Return, 50/50 Chance to Win: +EV betting for the player, with an expected value of 0.05 units, if 1 unit is bet. (0.5*1.1-0.5*1) No gambling site can afford to run with a -5% EV for a long time, they will probably run when they get a decent amount deposited.

Ref System Giving 0.5% of Winning Bet Profits: EV becomes -5.25% for the site (might have messed up my calculation for this one)

Promotions with Returns up to 200%: -55% EV for the site, if the return becomes 200%. Talk about unsustainable!

TLDR: The site is expected to lose in the long term, by quite a large amount.

Yup exactly what I mentioned but he just ignored and haven't replied to this .




Mate , 110% according to him is 1:2.1 so if you bet 1 BTC  you get 2.1 BTC and that's why it looks fishy.

Guess heads or tails to win 110% instantly ;D ;D ;D
110% is very low :o

what chance of winnings?

I think is not 50/50

If you think it is not a 50:50 game then what do you think? 110% for a 50:50 game is quite high if you have a good math. Other head and tail game only give less payout, this site gives 110% makes it so strange and suspicious.

usually head-tail game give min 180-195% with 50/50 chanche to win..
110% i not really.. because players use martingale strategy

Where you find a teals and heads game which give you 180-195%? If it is true then it would be the best place for gambler to gain profit.
180-195% means if you bet 0.001btc then you will get 0.00180-0.00195 profit. Too good to be true..but please tell me where I can play heads and tails with 50:50 chance and give 180-195% return. It is so +EV for players, and I believe there is single person in this world to make gambling site with so huge +EV for players.

it is mean that house edge 5-20%.
in bitflipy.com house edge is 90% really good profit for owner :)

Payout is too high and it saying guaranteed 110% fixed but there is no explanation about that, in case of losing streak how system will calculate the fixed return if balance get empty and we have nothing there, than how we get it back?

Guys please calm down.

110% win means that you exactly make 2.1x on your bet amount, that IS NOT 90% house edge...

Also max bet is now set to 100 mBTC (0.1 BTC) according to our max bankroll. Max bet is always far away under the bankroll so to avoid extreme bankruptcy.

I know this is a big % of win profit and maybe it could be disadvantage for the house, but this should be an incentive for users to play with. I'm not here to scam anyone (I won't ruin my reputation) and I'm ready to pay every win. If the game will make my bankroll vanish I will accept it as this is a bet also for me. :)

Hope you have fun and keep posting your feedback (contructive ones preferred please.)

So how can we know that you wont scam us? Any proof of your bankroll on cold storage that will pay us? 1-2 btc wont be enough as your cold storage as i know because you never know when or how much people will come though.

Btw is there anyway that we can check the provably fair system? 50/50 chance to get 110%? Dont get it on my mind though

the site looks simple but nice and the way coin flipped is so great
but why email/username and password form is seen blank on my side
is it because i use mobile device? What's the problem?

If players win and get 110%, you wrote wrong. It's return 210%.
2.1x for chance 50/50 not really!

Example:

Because if total bets 1000.
Wins 500 and lose 500 bets.
Wins bets 500x2.1=1050..

Your profit total bets - wins=1000-1050=-50

Do you really lost money? Or chance to win not 50/50.

Bitflipy is provably fair with seeds verification. Actual bankroll is 50 BTC and max bet is 0.1 BTC .

Having a 50% win chance doesn't mean that on 100 bets you win 50 times for sure.

Please read more about indipendent probability math.

Let HnHn be the indexed event of getting a head on the nthnth flip.

Given an unbiased coin, P(H1)=P(H2)=12P(H1)=P(H2)=12

These events are independent so P(H1∩H2)=P(H1)×P(H2)P(H1∩H2)=P(H1)×P(H2).  The outcome of one coin toss does not influence then outcome of the other.

You can learn more about statistics probability calculation here https://www.fourmilab.ch/rpkp/experiments/statistics.html or in any math book.

Really?

100 bets get average 50 wins.. 45-55.
for long period value limit to really 50/50.
for 1000 bets average 490-510 wins...
Please learn statistics probability

do you read your link  https://www.fourmilab.ch/rpkp/experiments/statistics.html

Suppose you ask a subject to guess, before it is flipped, whether a coin will land with heads or tails up. Assuming the coin is fair (has the same probability of heads and tails), the chance of guessing correctly is 50%, so you'd expect half the guesses to be correct and half to be wrong. So, if we ask the subject to guess heads or tails for each of 100 coin flips, we'd expect about 50 of the guesses to be correct. Suppose a new subject walks into the lab and manages to guess heads or tails correctly for 60 out of 100 tosses. Evidence of precognition, or perhaps the subject's possessing a telekinetic power which causes the coin to land with the guessed face up? Well,…no. In all likelihood, we've observed nothing more than good luck. The probability of 60 correct guesses out of 100 is about 2.8%, which means that if we do a large number of experiments flipping 100 coins, about every 35 experiments we can expect a score of 60 or better, purely due to chance.

So where is the problem sorry? Are you just fudding or what? If you are not ok with my game you can not use it.

The game is provably fair and this is what you should care of as user.

if really head-tail need set win 180-190% and players will not afraid it..
because high rate x2.1 like scam ( not mean your game)..

Any other game like this will payout 1.98x at max for a 50% win probability. So far Bitflipy.com is much more profitable than any other coin flipper out there.

Why not just gamble yourself? You can easily have a -1% EV on any dice site, or create your own moneypot app with a 5% edge to simulate the same -5% EV, while still making a 2.5% cashback on every bet. What is your bankroll, and can you sign a message with your cold storage, proving you are solvent?

Any other game probably has legit owners that operate for a profit, and therefore less likely to run.

You have a beautiful site up here but the betting method which you promote is the most prone to fraud one as seen by the defunct payment processors like liberty reserve (LR) and egold.
Try and include more bets in order for your website to have more exposure.

lol, I finally found the game head and tail using bitcoin payments, a good idea for a game that a lot of boring now like to roll the dice BTCBTCBTC

Things broke at our end, try another time.

10x0.0011mBTC=0.0110mBTC, where is my 100 sato?

Can you give us the proof that you hold 50 btc on your cold storage? How can we know that you really have this huge amount of btc without any proof? And can you still explain about 50/50 chance to get 110% payout? doesnt make sense though

Will post screenshot or sign message asap.

The 2.1x payout is a starting promotion. I was thinking about reducing to 2x later on when the business is estabilished.

I saw this interesting, I'll make an account there and try to play

I'm confused. Is BitFlipy truly operating with a negative expected value and planning on operating with a neutral expected value later?

Darkstar already calculate about their site being -EV and that doesnt make sense why there are site with -EV. There is no point if the site with -EV still operating it because they wont make any profit in the end. So this thing will turn out become scamming site. From Darkstar point of view

I read that, but I'd like CryptoGore to confirm it. Perhaps he is not aware? ???

I believe he is aware about what he offers on this site, as shown on his post :

Not really sure how long he can keep this +EV for players, I think it is just like a launching promo. Would be bad for gambling site owner to run -EV for the house for long run.

Thanks for your feedback.

As said I have a good knowledge of statistics and probability so I'm not going to explain further more than the links i briefly posted, I'm aware however that this -EV can set me on bankruptcy, but the odds are really low for this to happen.

As also specified this 2.1x payout is a incentive for players to come and try their luck until the game is not established, then i'll lower the payout bet to more standard rates.

Then you certainly understand that with a sufficient number of wagers the probability of going bankrupt with a negative house edge approaches 100 %. It still seems reasonable as a temporary measure to attract new players, though something like a deposit bonus is probably more effective.


If you only reduce the payout to 2x, as you mentioned in another comment, then you would be operating with a neutral expected value. Assuming you have fixed costs the probability of going bankrupt still approaches 100 %. In any case you would be taking on a large amount of risk for no expected return.

To explain why this makes some people anxious: For a rational operator of a successful casino the incentive to steal deposits is offset or even eliminated by the fact that operating the game legitimately is profitable. If you cannot expect to profit from operating your casino legitimately, the incentive to run with the funds is infinitely greater, relatively speaking.

Up.

What is the number range for boths tails and heads? I have just tested with the test balance, all bets on tails are lose. All numbers is a lose if I bet on tails.
Seems that this site has the same bug with bitcoinflips, where players has no chance to win when they pick on tails.

Didn't you notice it? Please take a look at this bug and please deactivate the deposit to avoid players losing their money because of this bug.

if I make a deposit bitcoin takes how long it would look at my account balance considering it may take several confirmed

I've gotten this PM from CryptoGore, a long with a (retaliation) -ve trust feedback.


I won't be doing anything, though I did decide to post it here. Would you trust an owner who threatens people when they discredit them/their site, and lieing about it in an attempt to get it removed? (read bold). Also, my feedback says this:
https://i.imgur.com/1hXuZ2X.png

My -ve trust feedback on you stated why I thought you were untrustworthy, which is a reason. I suspect he will delete his rating soon after seeing this, but it can't be archived.

Oh my god! Do you see it? Do you see the coincidence?

Orhan1337's "Flip a coin and win 200%" (https://bitcointalk.org/index.php?topic=1684589.0) uses the same software as CryptoGore's "BITFLIPY"! You can even see the same coin animation! That's why both of these have tails lose on every single roll! And you can even see the same misspelling of "Oops" as "Opps!"

What a wad of garbage.


Time to add to his list of negative feedbacks.

Hold on your willing to deposit on this site till they fix the bug. I believe you will not risk your btc on a site with a serious bug where players has no chances to win a betting on one of the option to bet (tails)

This is not true. You can win also when you bet on Tail, your assumptions are wrong and based on a small sample size, worthless for any statistical model.

VERY STRANGE THAT TWO USERS WITH SAME SIG AVATAR AND SAME STYLE OF WRITING LEFT ME NEG TRUST WITH NO REASON OTHER THAN SPREAD FUD.

VERY STRANGE THAT BOTH THESE GUYS ARE FROM THE SAME CITY??? AND THEY GO OFFLINE AT THE SAME HOURS? THEY ALSO HAVE THE SAME POSTS ON THE SAME THREADS....WHAT A BUNCH OF FAKE SCAMMERS

actmyname is an ALT of darkstar, that's obvious. You're ridicolous guys.

If I win 110% when I flip a coin, it seems that I get the advantage. I am curious what is your gain?

Ok guys, I will set win amount to 100% so everyone here will be happy to gain less and give me more coins ;).

So maybe the FUD will stop.......

Luckily you have not received red trust from DT members while the owner of the copy site (bitcoinflip) has received red trust from Lutpin but be ready, sooner or later you will get the same as what Orhan1337 (https://bitcointalk.org/index.php?action=profile;u=496052) got.
If you do not want to get it then you should know what to do with your site.

I didn't know that this "Canada" thing above the U.S.A was a city... Since everyone that lives in Canada is an alt of mine (over 35 million), oh wait they aren't.

It's not like there's a campaign (https://docs.google.com/spreadsheets/d/1jsxylSg7aOm2I9AjC3d3sBeqcXaeOzmSHe5g0XThibQ/edit#gid=1977927627) that requires you to wear the same avatar and signature to get paid. (Over 20 alts here! /s)

I didn't know that people could be fluent in English. Hmm, learn something new everyday.

If I operated a site where I said "Give me your money and I'll give 5% back, instantly or up to 55% in a promotion!", would you think it was legit? No. That was basically what you were saying, except with a small risk of the person losing their money.

Learn about time zones. Not everyone has a unique time zone, and I wouldn't be surprised if our time zones were close to each other. Slightly different posting times though: (mine first)

Anyway, if you find any actual proof, maybe make TruthBeTold happy and finish the accusation here. (https://bitcointalk.org/index.php?topic=1591618.0)

Could you please tell us how to win on tails? At least give me the range numbers to win on tails? You cant say that small sample size is worthless for any statistical model. Although it is only small sample, but it is a fact that there is something wrong with your site. If you dont care about this small thing, means that you will not care about big issue as well.

Now site is broken, cant open

So do you even try to place some bet on heads? Because if you said your bet on tails keep on losing that means you will win if you keep betting on heads right? Unless this site is rigged and make all of your bet is losing only some wins

Sorry, BTCevo (https://bitcointalk.org/index.php?topic=1206112.msg16990068#msg16990068), but you're not understanding. It is impossible to win with tails. Regardless of whether the roll number would have resulted in a heads win or not, tails will always lose. Always. On the site, it states, "For tail, get a number between 4900 and 9898 (or these)."

The numbers panjul07 submitted surely are in the range. Hence, this is a scam.

I appreciate your constant FUD here, seems my game is worrying a lot of person, maybe is that so good that it needs a constant FUD? Thanks sock puppets for keeping up my thread anyway.

HOWEVER: what you say IS NOT TRUE. You can win also with Tail as you can win with Head with the same winning chance probability. you posted less than 10 games and you want those values to be representative of all the games? Statistical models don't work like this FYI. If you could check a larger number of bets you would see that the games gives wins with Tails too..

Works fine for me won both on tails and head. good game.

It was true that there was no chance to win on tails. If there was a chance to win on tails why my bets with rolled numbers over 4900 were lost?
But seems that you have fixed the bug, now I can win on tails with rolled numbers over 4900. Just curious why you did not admit that there was a bug on your site?

Edit : it has nothing to do with statistics IMHO, even if there was only one losing bet that should be a winning bet then there must be something wrong with your site. You cant ignore a little mistake on your site. Once again I ask you, how could my bets with rolled number over 4900 were lost? Can you give me a logic answer?

Where is the faucet Sir?

Did they say that they have faucet? Afaik there is no faucet here, they only give you some bits upon registration. Did you get the free bits?

Yep i did, my mistake. However this games seems good enough to me and the provability fair is good and safe. I think there is too much non-sense FUD in this thread...Keep up the good job CryptoGore ;)
