1  Economy / Services / Nodejs developers wanted to work on gambling site (BetKing) on: April 30, 2017, 02:45:52 PM
Looking for Nodejs developers to start immediately on gambling website.

Must have experience with event sourcing and CQRS, Microservices and TDD.
Will also be using, Postgres, Redis, RabbitMQ and Express.

If interested send a pm with a link to GitHub profile and portfolio with relevant experience detailed.

Even better if you have worked on an existing Bitcoin gambling site.



2  Economy / Gambling / Relaunch - GET REWARDS - Multi-currency, Create your own app on: March 26, 2017, 01:06:05 AM
Preview 1:

I've just uploaded the first public preview of the new site to a test environment where you can try it.

This version is an initial "preview" of the dice game with multi-currency and "apps" support.

There are some features missing that you would expect like bot etc
These will be added asap as part of the "Preview 2" release.

Also you can see a sample app at which allows you to login with your BetKing account and play.

Since this is just a test version there is no actual deposit or withdrawals.
You can fake a deposit by selecting your currency in the drop down of the main site,
and then using the same dropdown to choose "fake deposit", this will add 10
of whatever currency you chose. You can do this as many times as you like.
This has to be done on the main site, not the app.

Creating an app:
I've uploaded the app sample code to GitHub where you can use it to test creating your own app. Instructions in the readme.
That also shows the roadmap of features to come in preview 2 for the sampple app
source code in the issues section.
You should be able to get it running on most hosts with no trouble but pm me if you need help.

Bug report/ feature requests:
If you find any bugs on the main site and have a GitHub account you can log
a bug here
That's where you will see current issues and planned features for the main site.
Please search the current issues to see if your bug has been reported already before submitting.
You can add bug reposrt/feature requests to sample app too.

If you don't have a GitHub account just pm me on btctalk and I'll log it.

If you are a javascript programmer you can submit pull requests for features or bug fixes to the sample app repository.
There's a list of issues marked with the Front-end label which should be able to be implemented without anything else being added to back end.
You can also submit code for features or fixes not on the issues list if you find something yourself.

Be great to hear your feedback.

Anyone who tests will be rewarded on the new site when it is live with bug reporters getting a larger reward, especially for security issues.
Also anyone who contributes code, fixes or features or even tidying things up, will be rewarded when the site goes live Smiley

Reward system/value to be decided still.

4  Alternate cryptocurrencies / Announcements (Altcoins) / [ANN] ICO - Bitcoin Gambling website - 581.4 BTC raised so far on: November 29, 2016, 07:47:54 AM ICO Crowdsale

STARTS: December 1st 2016 at 0:00 UTC
ENDS: January 1st 2017 at 0:00 UTC

Funds raised so far: 581.4 Bitcoin

About BetKing: is one of the oldest Bitcoin gambling sites, launched in April 2013, and has since grown to become the most trusted and one of the most popular Bitcoin gambling sites with over 397,000 Bitcoin wagered and earned over 7200 Bitcoin profit.

I am looking to make BetKing and Bitcoin gambling grow even bigger and inviting you to be part of it and share the success.

  • Launched April 2013
  • 397,500 Bitcoin wagered
  • 7258 Bitcoin profit
  • 353,000,000 bets
  • 8500 accounts

Why should I invest?
BetKing is one of the most well known Bitcoin gambling sites and has been the most profitable crowdfunded site with over 7200 Bitcoin profit in the past 2 years alone.

It has seen the most wagered volume of all other crowdfunded gambling sites, more than almost all others combined.

This popularity and profit has been from one game and very little marketing.
Our simple to play provably fair dice game.

We are looking to raise investment so we can develop more products including our own provably fair casino games such as blackjack, slots and roulette.
Funds will also go towards developing a sports betting platform, poker software as well as a host of other gambling related products and services.

Due to the success of BetKing and the previous crowdfunded platform I now have many contacts in the industry who are experts in each of these domains who we would work with to build the best products possible.
With your help we can market each of these products to grow BetKing into the leading Bitcoin gambling destination.

Note: BetKings bankroll was previously funded by crowdfunded investment which totalled 6000 Bitcoin. From the 1st of December BetKing will be privately funded and all current investors divested.

BetKing will create 100,000,000 tokens (100 million) to to represent 100% shares of BetKing, currently owned fully by me.
No new tokens will be created.

30,000,000 (30%) of these tokens will be be sold to investors during the ICO period and distributed at the end of the fund raising period.

The remaining 70,000,000 (70%) will remain in the ownership of me as my 70% equity in BetKing.

The funds raised by selling these shares will be loaned by me interest free back to the company to use for expenses and bankroll.

Threshold: 2000 Bitcoin
If the crowdfunding campaign fails to reach the goal of 2000 Bitcoin invested all funds will be returned.

Early investor bonus:
Early investors will get a larger percentage of the shares from the crowdsale meaning their coins will have more weight or purchasing power towards the percentage of shares you receive.

Week 1 = 10% bonus - December 1st 2016 at 0:00 UTC to December 7th 2016 at 23:59:59 UTC.
Week 2 = 5% bonus - December 8th 2016 at 0:00 UTC to December 14th 2016 at 23:59:59 UTC.

ICO starts at December 1st 2016 at 0:00 UTC and ends at January 1st 2017 at 0:00 UTC.
After the ICO has ended, 30,000,000 shares will be distributed proportionately if the target of 2000 Bitcoin or more is raised.
E.g. if we collect 2000 BTC and your investment is 200 BTC, you'll receive 3,000,000 shares.

These shares will be added to your BetKing account where you will be able to trade with other members on the BetKing website.

We will pay dividends as a share of the total profit (revenue-expenses) generated by BetKing in Bitcoin directly to your BetKing account every 3 months if the total capital is greater than the 2000 Bitcoin loan.
You can withdraw your Bitcoin dividend payment instantly to your own wallet.
This may change to be more frequent, e.g. a month, after the first dividend payment.

For example:
Assume revenue from players losses were 300 Bitcoin in the first three months.
Imagine we paid 5 Bitcoin for fixed cost expenses, 10 Bitcoin on banner ads and 10 Bitcoin on developer contract.
After the 3 months we have 2000 (the initial loan) +300-5-10-10=2275.
275 profit.

So the investors from the ICO would get a dividend share of 82.5 (30% of 275) paid into their BetKing account.
I would be paid 192.5 (70%)

The business would have 2000 Bitcoin left in it from the intial loan.

Another example:
In 3 months players win 100 Bitcoin playing dice.
We paid 5 Bitcoin as fixed expenses (server, cloudflare etc).
We spent 10 Bitcoin on some banner ads.
We spent 10 Bitcoin on a contract developer.

After the 3 months we have 2000-100-5-10-10=1875.
-125 profit.

So there are no dividends to be paid as there was no profit in this time.

The business would have 1875 Bitcoin left in it and no dividends would be paid until this amount was over 2000 again.

What the funds be used for:
Most of the funds will be used for but are not exclusive to:
  • Bankroll for players to bet against.
  • Development of new products.
  • Marketing

Exit Strategy:
If BetKing were to be closed for any reason or lost market share to where it stopped generating profit then the initial loan would be paid back to me and then any extra funds left in the business not paid out as dividends yet would be split 30% to investors and 70% to me.
Any assets including the software could be sold and 30% of the sale price distributed to investors.

HOWEVER if BetKing was forced to close suddenly within 3 months of the ICO then all existing funds in the business at that point would be used to pay investors back as close to their full initial investment as possible before I took any share.

There’s also the possibility in future for BetKing to be acquired by a bigger company in which investors will share 30% of the total sale price after the initial loan is paid back to me.

Proof of funds address:

How to buy shares:
To buy shares during the crowdsale period you need to sign up or login to and deposit the Bitcoin you wish to invest, or use the existing balance you have.
You should then visit the invest page which will be live on at the start date of the ICO and enter the amount of Bitcoin you wish to invest then click invest.

If you have any questions feel free to ask by posting here, private messaging or emailing

7  Economy / Securities / - FOR SALE - 7100 BTC PROFIT - Bitcoin gambling site on: November 10, 2016, 10:05:14 AM
Announcing is for sale.

About BetKing:
BetKing is one of the oldest Bitcoin gambling sites, launched in April 2013, and has since grown to become the most
trusted and one of the most popular Bitcoin gambling sites.

BetKing offers the best provably fair Bitcoin dice (Hi-Lo) game.
Fast and easy to use with the largest max payout of any other Bitcoin dice site, 185 Bitcoin.

Here is the main Bitcoin Talk thread:

Over the two years BetKing has become the most trusted gambling Bitcoin site with a crowdfunded bankroll of 6200 Bitcoin.
Profit is over 7100 Bitcoin in past two years, most of which is this year.

Why Sell?
I have worked full time on BK for 3.5 years and I have some other projects I would like to pursue.
The right buyer would be able to improve BetKing for existing users and grow much larger than I can do alone.

What you get
The buyer will get full source code to the website, all domains related to BetKing and all social media accounts.
You will also get training and tutorials for running the day to day operations.
I will help you deploy the code to a new server.
I will also offer 2 months free support if you need it. This does not include adding new games/features.

What you don't get
Although currently BetKing has a crowdfunded bankroll a sale would only be made to someone who can provide their own bankroll.
You would want at least 800-1000 Bitcoin to keep BetKing having one of the highest max payouts but it could be less.
Any current investors would be cashed out before transfer of assets.
Any potential personal details of user accounts will be removed.
Gambling License. You will need to check the laws of operating a Bitcoin gambling site in your country.

Serious offers
Only serious offers should be made from buyers who can provide their own bankroll.
Offers should take into account the past profit of 7100 Bitcoin.
You can email or pm on here. I can provide a pgp key if needed.
Profit/wagered stats for all games will be provided in a detailed report for serious buyers.

If no sale what happens to BetKing?
If there are no serious offers or I feel that the buyer is not going to run BetKing legit or to the standard that players expect then I will not sell and continue to work on improving and running BetKing as normal.
I am not looking for a rushed sale.

Feel free to ask any questions here or on email/site chat etc.

8  Economy / Services / Looking for a signature campaign manager on: November 03, 2016, 04:37:20 PM
As the title.

Here was the last one we run
I believe Yahoo is running a different sig now or has an app.

Going to try this for longer this time with a bigger budget too, maybe until the end of the year if it's going good.

The manager must take care of every aspect of the campaign including:
registering users
checking for multi accounts
making sure no one is switching their signature at any time during the campaign (best to show me a script you use)
payment to users at the end of each week (I will obviously supply the funds)
define rules
deal with any queries or complaints from participants
manage and update a public spreadsheet showing users/payments/post counts etc (prefer if this was automated too)

I think ndnh has run campaigns where everything was automated so check out his previous campaigns and spreadsheets.

You must have run a large campaign before, post links.

11  Economy / Services / Boost my page rank - 5 BTC reward! on: September 22, 2016, 05:26:52 PM
Hi guys.

Quick intro if you don't know

BetKing is the most popular crowdfunded bitcoin dice site. We have more wagered than all other sites (more than most of the biggest combined).
We are the most trusted crowdfunded dice site. We have a bigger bankroll than all other sites, 5k btc, more than some of the other biggest combined.
You can view proof of this on

Yet we are listed on page 4 of Google for the term "Bitcoin Dice" even though there is only one site more popular, Primedice.
I think Google has given us a penalty or something but don't know why or how to check.

The goal here is to find someone who can boost our page rank, not using blackhat techniques, so that we are on page 1.

The person would submit a plan of action on how they will accomplish this (via pm).
They would manage all tasks, say for example creating blog content.
Payment would be done in two installments. Once we get to page 2 they would receive 2 Bitcoin and once on page one they would receive the remaining 3.

We have a new light themed homepage, blog and dice game page designed and it should be live within the next week so that should help.

Almost all competitors have little or no social media activity.

Almost all have little actual wagered and are either free faucet players or bots so not much real traffic.

Feel free to ask any questions that may help.

13  Economy / Securities / Investor thread - 7079 Bitcoin profit, 6260 Bitcoin invested on: July 31, 2016, 06:06:33 PM
I decided to make an official thread for investors of here where I'll do a weekly list of investments with total invested.

Feel free to ask any questions, I may have forgotten something in this first post.

For daily and total wagered, profit, bets, invested stats visit to get data going back to November 2014.

To anyone new: has been open for over 3 years now and has become the most trusted and popular crowdfunded dice/casino site.
We have the most invested, the most wagered and the most profit of all crowdfunded sites.

At this time there's 7079 invested with 393,319 wagered and 6260 profit. charges commission by taking 25% of the weekly profit (made from player losses) and 25% of the edge on wagered amounts at the time of bet whether the player wins or loses. The weekly profit commission is only charged on new profit.

The crowdfunded bankroll is used on the dice and social dice games. Everything else is funded by

To invest click on the site bankroll link on the left menu of the site or go here

Proof of funds:
We used to keep all investor funds in one cold storage address so that investors could make sure their funds were still safe.
I decided to change to the method of keeping the cold storage addresses private as players were reporting that exchange sites like Coinbase were closing peoples accounts.

I know this is a massive red flag for potential new investors.

I have run the site for a long time though and built up a lot of trust and I am open to the idea of having a trusted member do an audit to prove I still have the funds every few months.

This was last done by dooglus on 7th July 2016
I sent dooglus a signed message from Betking cold storage addresses that he can verify and prove solvency.

I received a signature for a message that said:
  'this is a betking cold storage address'

The address which was used to create the signature contains a little over 4500 BTC.

Dean tells me there's ~100 BTC in the hot wallet too.

So that's a proof of assets. For real proof of solvency we would also need to see a proof of liabilities (ie. investment amounts) to make sure that liabilities don't exceed assets. The danger is that there are 10 investors each having invested around 1000 BTC, so the total liabilities are over 10k. I'm not suggesting that this is the case, merely that it is possible if each investor doesn't have a way of making sure his coins are counted in the claimed total.

Proof of solvency:
As dooglus pointed out above just because I show I own a certain amount of funds doesn't prove solvency.
So here is a list of all invested amounts over 0.01 (user id's removed).

14  Economy / Gambling / Social Dice Provably Fair seeding event - on: July 14, 2016, 08:06:37 AM

We launched a new community dice game, Social Dice, at a couple weeks ago and it was pointed out by RHarver that it wasn't actually provably fair.

He kindly said we could use the same method he uses at Bustabit to ensure our multiplayer game is provably fair. We only changed it a little.
You can read more about it in his thread

It works like so:

1) We generated a chain of 5 million sha512 hashes starting with a server seed that we randomly generated. So we take the sha512 of our server seed and then we take the sha512 of this hash and so on 5 million times.

The sha512 of the final hash is:
A86FE6011E456DDEF66FCAD16A16EA063746A718D7542B5C50C362D1D9792F4C458E4C71DD8F87D F5F8BB4679304671AC9B1E60FC089F4CA745437AEB897646F

Posting it here means we can't pick a different chain in the future.

2) The final hash will be the hash of the first server seed used to generate a roll in the Social Dice game. We will then use the previous hash in the chain for the next round and keep playing through these hashes in reverse order.

3) So far we have only generated a chain of server seeds and that could allow us to choose a chain that favours a certain outcome so to make sure we can't do that we also add a client seed that we don't have any control over. The client seed will be the block hash (all lowercase) of a Bitcoin block that is not yet mined, block 420731.

EDIT: The hash of the block 420731 used as client seed is:

The first round was 41480

This server seed and client seed are fed into the exact same roll calculation method that the regular dice game uses.

I will update the provably fair help page on BetKing to detail this change and give code you can use to verify your results.

Thanks again to RHarver for giving permission to use and to Dooglus, Eric and Steve for their work developing the method which is detailed here
