521  Economy / Gambling / Re: [hashdice.com] best dice bet game ever with crowedfunding on: June 26, 2013, 10:05:03 AM
In my opinion,abandon a block is just the same as didn't participated in mining a block,so odds won't change.

That's nice, but it is not a matter of opinion.

If I bet heads on a coin toss, then toss a coin, see that I've got tails and so throw the coin away and let you make the 2nd toss, don't you think I have a better chance of winning?

HH = win
HT = win
TH = win
TT = lose

I have a 75% chance of winning if I'm allowed to abandon the first result when I don't like it.

I like the idea of letting your players bankroll the site.  You're a genius!  Smiley
But the blockhash is the result of proof-of-work,you don't have a chance to make the 2nd toss.

Yes you do, you do not have to broadcast your block hash. Let me work this out step by step to you:

You bet 100 btc on hashdice.com. 50% chances.

You find a block. You calculate the block hashes...

(a) You win the hashdice bet! You publish your block. 50%
(b) You lose the hashdice bet! Sad You don't publish your block. Now two things can happen:
(b1) Someone else finds a block and you win the hashdice bet! 25%
(b2) Someone else finds a block and you lose the hashdice bet! 25%

EV = 2 * 0.5 + 2 * 0.25 = 1.5

The miner can choose to NOT broadcast the block IF it won't win the bet. If it WOULD win the bet, the miner would publish. It lets them roll the dice twice - the first roll is choosing to publish it or not, the second roll is another miner mining.

Or don't bet money until you found the block, then include the transaction and broadcast it yes/no.

I do not understand how half of the games work. Is there any game explanation on the site?

Sorry, but your site does not look legit at all.

For people not believing this is possible and posting screenshots as proof:

the tl;dr part: the odds that make the bookies lose disappear VERY QUICKLY and sites may disable your account.

The popup box says Your bet is invalid, valid bets are ฿0.00000001 to ฿10000000.
But when you enter anything above 0.1 it tells you it's too much.

Increasing the wager should never affect the chance of winning (or vice versa)

The outcome has nothing to do with the "luck" value shown.

What is your gambling license?

If you are not licensed, you are violating the law!

THIS IS A SCAM AND ILLEGAL

A few governments already stated that they do not see Bitcoins as actual money and therefore it is a novelty item without any worth. So you are gambling with $0.00 bets with a payout of $0.00 per bet. Therefore, in countries that do not see Bitcoins as money, it is not covered by the regular gambling laws since there is no money lost/won.

your accounts might get limited/suspended

At least with the big books like unibet, bwin and toto I would not worry about this since they are closely watched by governments (whereas Toto is even owned by the Dutch government) and suspending accounts for betting on weird odds is not something covered in the terms of usage (and if they would add that in their terms one could question them why they offer these odds then).
This is indeed an issue on smaller gambling sites though.

the bookies for this arb accept what's called an Asian Handicap.

http://en.wikipedia.org/wiki/Asian_handicap

Thanks, I did not know about this and thought I found an obvious flaw in your strategy Cheesy
Instead I learnt something new.
534  Economy / Gambling / Re: Win Every sports bet you make. Every Time. on: June 23, 2013, 12:55:12 PM
Spain (u20), NordicBet: 1.37
Ghanna (u20), BetClick: 12.0
Asian Handicap

1. Neither of these two sites were named in the initial post.
2. You do not account for draws in sports where this is possible.

If anyone can think of a better way of calculating "how lucky" the players have been (individually, and as a whole) I'd love to hear it!

Somehow relate the luck to the wagered amount, so a single win with 1 satoshi on 0.0001% does not get the site's luck up from 50% to 250%.
536  Alternate cryptocurrencies / Service Announcements (Altcoins) / Re: Just-Dice : FREE BTC : Play or Invest on: June 22, 2013, 06:13:15 PM
Here's how to make people who invested earlier gain more:

Imaging a user bid 1 BTC on 50/50. This means, out of the pool of JD, 1 BTC is wagered against him (well, actually 0.99 BTC but for simplicity I put 1).

The question is: whose BTC is being wagered against the user? Right now, it is taken from all the investements in equal proportion. What can be done instead, is that it is taken from all investments *weighted* by the time they invested they made the investment. For example, 1/5 BTC from the first month's investments, 1/4 form the second etc. In fact, better use slower decreasing weights to make the investement attractive for new users as well. For example,  [1/k(k+1) - 1/N(N+1)] weight for the BTC number k, with N being total number BTC invested.
Obviously, the wins/losses then are devided in this proportions.


one issue with this is that a common pattern could be:

divest all
gamble
invest all


I don't see how that could be a problem. If you divest and then reinvest then of course your investement moves all the way to the end of the line, and will be earning less. Wheter you gamble in between doesn't matter.
No. Let's say you are really good at this game.
You take away your 1000BTC investment. Now you use your gambling skills to win back all the other investments with your 1000BTC. You know have, let's say, 2000BTC.

You now own the entire bankroll. You invest it all. Congratulations. You own all the site's money.

Whooo! I won the hardest bet on the site: >99.9998!
If you could dig up the link, dooglus, that'd be great. I seem to have pushed it off the page.

After how many 0.00000001 bets?
538  Alternate cryptocurrencies / Service Announcements (Altcoins) / Re: Just-Dice : FREE BTC : Play or Invest on: June 22, 2013, 02:46:52 AM
You stole the millionth bet and the first million-to-one win, but I will be the first to win the "technically hardest" bet!

If you don't have it by tomorrow morning I will beat you to it Cheesy
539  Alternate cryptocurrencies / Service Announcements (Altcoins) / Re: Just-Dice : FREE BTC : Play or Invest on: June 21, 2013, 10:36:46 PM
As linked twice already, the second to hardest bet has been won once already: Roll exactly 0.0000

Second to hardest?  What's harder?

99.9999
It occurs a little bit less as you should know.
540  Alternate cryptocurrencies / Service Announcements (Altcoins) / Re: Just-Dice : FREE BTC : Play or Invest on: June 21, 2013, 09:10:56 PM
Going to be trying the 1% edge, or .001% edge one day. Guessing nobody won it before, so hopefully I am the first.

(Yup, going to lose all of my Bitcoins on it.)

As linked twice already, the second to hardest bet has been won once already: Roll exactly 0.0000
