Your a good guy and all, but what the hell makes you think people want to chuck you upwards to $100k worth of Bitcoins to make a -EV gamble?
If people want to bet, they'll bet themselves... It just makes me cringe seeing you constantly post/ask for people to trust you with absurd amounts of money. Your offering 1% on an investment which if fails you have no way to pay them back. And that's already on top of your -EV you will receive from gambling. That means their EV has been drastically reduced even further. It just doesn't add up what so ever. Your also claiming to be 'professional' at rolling a dice? I can't even begin to grasp that, come on Dabs...
Your a really smart guy, find something productive to do with your time.
I don't (think people want to send me money, to just gamble randomly.) It's a gamble, and that is quite clear from the start. It's -EV yes, but I'm positive at this point. They can bet themselves, sure, but do they have the time or patience to do literally a million bets? That's the plan anyway, not a single big bet that doubles your money with half the chance of losing it all. I think I'll stop the asking part (on this thread anyway) since it bothers you. I'm talking to the whales who are going to bet big anyways. The "investment" is also a joke. I will make it clear that if I lose, I don't pay, since I can't pay. That's why it's called gambling. There are no sure funds, not even mutual funds or stock markets. They all have risks. The risks are low, but there are still risks. But the payout, if I win is big. Or at least more than any other investment that is not gambling. I consider mining to also be gambling, with the increasing competition and rise in difficulty. What investment managers do is mitigate those risks to produce profitable returns. And some other things I guess. I'm not claiming to be a pro, I said I just feel like it. (on an unrelated note, I was undefeated in Starcraft 1 in my entire school on both 1-vs-1 and team games, about 800 students, and I was 2nd place in a chess competition once.) In gambling, the house always wins. But there are also players, and for everyone that losses, there are also winners. The posts above already indicate the probabilities, so I won't repeat them here. What I'm saying is I can duplicate the same probabilties, calculated over time or over hundreds or thousands of bets, to come out with the desired results, and if you bet right, you can win. You can also lose. I think I better make sure that part is clear. You can lose. Your a good guy and all Thanks. I'm a good guy, doesn't mean I can't gamble every now and then and have fun. It's more fun to gamble with more money though, I think you can agree with that. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) find something productive to do with your time. I spend only about 15 to 30 minutes reading the forums per day. I spend about an hour determining the winners of my lotto. I go watch a movie in the theater once in awhile. I lift barbells for 45 minutes 3 times a week. Every other weekend, I'm on a medical mission distributing relief goods to disaster stricken people. I'm in the Philippines, by the way, and half the country is poor. The rest of the time, I'm either at the office, working like everyone else, or at home, spending time with my 2 kids and the wife. oh, yah, I'm on just-dice chatting with the nice people there (including you.) and telling dooglus about any bugs or typos I find on his site, and getting comped 0.01 for that. Then I let the bot run while I am asleep. It doesn't matter if you do a million bets. You haven't changed the odds, what you've done, since this is a -EV game, is lower your return & thus your expected profit whilst decreasing your chance of variance (And as a bettor, playing a -EV game, you want HIGH variance). Gambling at -EV compounds as volume increases. You doing many small bets is detrimental, you haven't changed the odds or anything of the such, you have simply gone 'slower' through manipulation of the probability of a sequence, at the cost of higher volume. The idea of martingale (Or any variation) can sometimes be productive when attempting to break down risk when playing games where the odd's are static. You can manipulate those odds successfully through applying a martingale methodology, allowing bettors to assume odds like 87.5% chance of gaining the respective 'base stake' profit if playing a 50/50 martingale lose & double sequence three times. This indeed has higher -EV than if you did one bet, but it allows the user to manipulate the 'static' odds given by the host. This comes at a cost though, since your 'covering' bets through excessive volume which isn't altering odds. The great thing about Just-Dice though, is it offers any odds you want, allowing you to disregard the need for sequences or strategies. This saves you volume, and with saved volume comes saved -EV & a higher level of variance for you to work with. Also, by no means could this ever be related in any way shape or form to an investment. When someone invests, they will always be attempting to gain a +EV through their investment. There is NO way you can obtain that through gambling, and thus gambling should NEVER be confused with an investment. Gambling is a form of entertainment, nothing more, nothing less. Stop preaching unrealistic theories & nonsense.

I want to tell you you're wrong, but I'm not sure what you're saying. What does "higher -EV" mean to you? I believe if you want to double your balance, you have a better chance of doing it using a martingale progression than if you place a single bet risking your whole balance at 2x payout. Is that what you're saying?

Therefore, martingaling or any form of betting progression is detrimental if your playing with house edge. Correct me wrong if I'm wrong. Edit: "Higher -EV" means that you've bet higher volume

Yeh. If you want to double your balance, bet it once on 2x rather than martingale. You will pay more "1% house edge" commission if you martingale. Therefore, martingaling or any form of betting progression is detrimental if your playing with house edge.
Correct me wrong if I'm wrong.
Yeah, you're wrong. Suppose you have 1 BTC and need 2. If you bet it all on the 2x bet, you have a 49.5% chance of doubling up. But if you bet 0.41421356 BTC on a 3.41421356x bet, and if you lose, bet the remaining 0.58578644 at the same odds, you still get to 2 BTC if you win either bet, and have a 49.58492857% chance of doing so. Better, no? (Every bet has a 1% house edge, meaning you expect to lose 1% of everything you bet. In the single large bet, you bet 1 BTC, so expect to lose 0.01 BTC. When martingaling, you expect to bet less than 1 BTC (sometimes you bet 0.414 BTC, sometimes you bet 1 BTC, average is somewhere between the two) so you expect to lose correspondingly less)

I think with a properly applied martingale, you can double or triple your money with better than 98% chance, compared to betting it once to double it on 49.5% chance.
If I'm wrong, then I guess I've been lucky over the last 900,000 bets.
You don't need infinite money, you just need enough to cover the longest losing streak you are willing to bet on, at the chance to win you are playing. On this site, this also means that the max bet on 87% is at least 1500 BTC, for example. On 98%, its more than 15k BTC. This, and the fact that you don't pay transaction fees compared to blockchain based dice games, some of which have 500 BTC max bet limits, allows you to play a longer sequence of martingale progressions before hitting the limit.
Of course, this also means that you have a small chance to lose everything. Small meaning less than 1%. It's not zero, therefore it is still possible to lose.
As to me personally disappearing with any amount of money that does not belong to me, I say there is zero percent chance of that. And I'm willing to bet on it, with my soul if you are religious, and with my life if you are after --whatever it is. On a more practical note, someone can make a bet on another site (bitbet comes to mind). Maybe an identity escrow would satisfy some people.
dooglus is also saying the same thing about not disappearing with 19k that has been invested in JD.
Unfortunately for us, this can't be proven. I guess in the bitcoin world, innocent until proven guilty just doesn't fly. You get accused of a crime that you will never commit.
On the martinfail of ZMan posted above, I've been telling them in the chat that 0.001 is too high a starting point. My initial bet on my 7 bet run, as can be seen in the screen capture, is a mere 2000 satoshis, and that is on 87%. At 50%, you have to start even lower to last long enough, as we've seen 40 loss streaks at 50%, and 111 loss streaks on 10%.
As per dooglus post before me, if you bet less, you lose less of the 1%. So if I am betting 2000 satoshis, I'm only losing 1% of that which is 20 satoshis. However I am winning 87% of the time. The 13% of the time that I lose, I attempt to gain it back by betting enough to cover the loss of the previous bet.

quote I was under the impression that no matter what you put into the "bet" or "chance" field, the expected value was the same: 99% return. Bet $1 at 50%: $0.99 return Bet $1 at 95%: $0.99 return I have not seen any math on the FULL probability and payout of a martingale, but does it break the laws of physics and offer a better return?

How can it possibly be that one bet for 2x at 49.5% gives a 49.5% chance of doubling 1 bitcoin to 2, but two bets of (2 + √2)x gives chance of doubling my money as 49.58% - see here for the full numbers. Well, the way I finally got my head round it, the house edge is against the amount you wager. In case 1 - you are wagering 1 bitcoin all the time, so the house takes 0.01bitcoins all the time. In case 2, you wager (√2 - 1) bitcoins if you win the first bet, and 1 bitcoin if you lose the first bet and subsequently win the second bet, so you wager less on average, meaning that the house takes less.

I was looking for a table like this. Martingale winnings: min bet: 0.001 bankroll: 100 Chance: 50% (Let's ignore the 1% house edge for now) Total win per round: 0.001 Chance to that you will loose everything: 0.xx% So I can compare that "chance to loose everything" with the chance for a regular bet.

Yeh. If you want to double your balance, bet it once on 2x rather than martingale. You will pay more "1% house edge" commission if you martingale. Therefore, martingaling or any form of betting progression is detrimental if your playing with house edge.
Correct me wrong if I'm wrong.
Yeah, you're wrong. Suppose you have 1 BTC and need 2. If you bet it all on the 2x bet, you have a 49.5% chance of doubling up. But if you bet 0.41421356 BTC on a 3.41421356x bet, and if you lose, bet the remaining 0.58578644 at the same odds, you still get to 2 BTC if you win either bet, and have a 49.58492857% chance of doing so. Better, no? (Every bet has a 1% house edge, meaning you expect to lose 1% of everything you bet. In the single large bet, you bet 1 BTC, so expect to lose 0.01 BTC. When martingaling, you expect to bet less than 1 BTC (sometimes you bet 0.414 BTC, sometimes you bet 1 BTC, average is somewhere between the two) so you expect to lose correspondingly less) Sorry, but I disagree Doog. I'm not referring to your first paragraph. That's just manipulation of multipliers. (Every bet has a 1% house edge, meaning you expect to lose 1% of everything you bet. In the single large bet, you bet 1 BTC, so expect to lose 0.01 BTC. When martingaling, you expect to bet less than 1 BTC (sometimes you bet 0.414 BTC, sometimes you bet 1 BTC, average is somewhere between the two) so you expect to lose correspondingly less) In order to profit 1 BTC from martingaling with a start of 1 BTC, with a base stake of 0.1 BTC, you would have to do a MINIMUM of 1 BTC worth of bets. (10x 0.1 BTC wins in a row). However, the moment you lose 1 of those bets & are forced to double up in order to regain losses, you're better more than 1 BTC. That essentially leads to your overall amount of volume increasing, which leads to a higher -EV. Martingaling is detrimental in -EV games. Edit: I think with a properly applied martingale, you can double or triple your money with better than 98% chance, compared to betting it once to double it on 49.5% chance. Dabs, you have to be kidding me... Right?..

Ugh.. Keep trying to win the one-in-a-million bet. Keep getting 97.66, though. ![Roll Eyes](https://bitcointalk.org/Smileys/default/rolleyes.gif) J-D addiction strikes again!

I'm not kidding. Why don't I post a little history of the experiment I made. I will do that later (or maybe not at all.) TL;DR = I deposited 0.4 BTC two weeks ago, I cashed out 2.0 BTC (including that last 7th bet) the other day. I bet almost a million times. That's a 5x return. In between I bought asic shares (off-topic) with what I won (that's another gamble). So I will not explain anymore the theories or the probabilities, I will just tell you what actually happened. You can argue and debate all year about probabilities, so I'd rather not explain to people who just don't get it, or don't want to get it, or don't want to believe it. But you can't argue with facts. It's not theoretical. It's applied. It's past. It's history. There are logs. There are screen caps. (You can argue that these are fake, I'll not waste time doing that.) Can I do it again? Maybe. Maybe not. That's the gamble. What I'm saying, is if someone funded me with 40, I'd have cashed out with 200. But I only had 0.4, so I only cashed out 2.0. The stakes don't change the results.

I've been arguing about this all day. I'm 100% satisfied that I'm right, but can't spend any more time on it. I would just say that you can profit 1 BTC from a single 0.1 BTC bet by betting at 11x to turn the 0.1 BTC into 1.1 BTC. I managed to convince a religious fellow in the Just-Dice chat that I was right after several hours of back-and-forth with him. He even paid out some of the bet I made with him on the subject, and ended up accusing me of "cheating" because I had obviously thought about it in advance... If I can convince him, I'm sure I can convince anyone given enough time. If only there was more time.

That's clearly ridiculous. With a single bet, you have a 49.5% chance to double your money. With the best martingale sequence possible you can approach (but never quite achieve) a 50% chance to double up. But you can't get higher than 50%. That would mean you had overcome the house edge, which isn't possible. You have anecdotal evidence of tripling up. That proves nothing about the chance of it happening. I can triple up by betting on a 3x payout. If I do it once and win, that doesn't show I had a better than 98% of winning.

I don't have the time to convince anyone, and you know I am a math fail most of the time. hehe. I made my money by buying stuff for $1, then turning around and selling them for $3. Those 3%, they add up over time. Math Fail. But anyway, can I still play? It's more fun to bet nine hundred thousand times than it is to bet once. Also, another but. You were the one that told me that the odds for 6 consecutive losses in a row on 87% was about 1 in 300,000. If that were true, then the chance of not losing 6 consecutive times in a row is 0.99999666666666666666666666666667 or 99.9996% Another math fail? edit* the house edge only counts if you win. If you lose, it doesn't matter, you lose everything, house edge or not.
