Bitcoin Forum

PolyCash (https://poly.cash) is the ultimate open source gambling protocol.  PolyCash integrates with Bitcoin, Litecoin and other blockchains and makes it easy to create a cryptocurrency for betting on anything.

We recently launched eSports Live $10k (https://poly.cash/esports-live-10k/).  This is a game for betting on CS:GO, Dota 2 and League of Legends using a stablecoin called "bucks" (USDB).  This colored coin runs on the Litecoin network and is backed by $10,000 in real dollars.

To bet on eSports, you first need to acquire some bucks.  Bucks are not listed on any exchange, so for now, you'll need to purchase bucks by depositing BTC to one of the public nodes hosting the eSports Live $10k crypto asset, such as https://poly.cash.  Your BTC will immediately be converted to bucks based on the current USD/BTC exchange rate.

You can set up a wallet by either:
1. Installing Litecoin, PolyCash and eSports Live $10k on your own computer.
2. Creating a web wallet on a public node like https://poly.cash

Now that you have a wallet and some bucks, bet on as many eSports events as you want.  eSports Live $10k charges a fee of 1% on each winning bet.

You can sell out at any time by entering a Bitcoin address.  Buy-ins and sell-outs are not quite instantaneous because one confirmation is required on Bitcoin or Litecoin.

This is a maximally decentralized betting platform and there's no house taking a cut.  Instead, the 1% fee is destroyed, reducing the supply of bucks.  The supply of bucks decreases as more and more betting fees are paid.  But the $10k backing this currency remains constant, causing bucks to grow in value vs the US dollar.  PolyCash is a pioneer of a concept called the "fixed term token" in which pegged coins are wound down for the sake of transparency rather than living indefinitely. eSports Live $10k will not live forever, and at some point this stablecoin will be wound down and the $10,000 backing it will be paid out to the coin holders via the Litecoin network.  We have not yet set an end date for this $10k stablecoin, but will eventually do so based on feedback from coin holders.

This eSports betting game is pegged to the dollar but we can just as easily create coins pegged to bitcoin, eth and more.  We can also integrate data sources for betting on other topics like sports or stocks.

This project has been under development for a while and the concept has changed significantly since we got started.  Please help us revolutionize the betting industry with open source software by making some bets with BTC or posting any questions or comments in this thread.

Betting using stable coin "Bucks"? ??? Inconvenient, why not accept direct bitcoin or any other crypto instead. Would have been better if you would directly let players bet than letting them buying a stable coin that is not traded yet.

^I would see this stablecoin usdb they are using on the site more like a token to be traded for the more well known coins once you want a withdrawal processed.
This seems to be the route more and more crypto casinos are going towards offering their own token system to bet with.

Because the whole platform is working on Bucks and that's just the way they've designed it. This whole project is all about their stable coin and they want to concentrate on increasing it's price until eventually they are going to pay those $10k to all coin holders. He explained everything, all you have to do is read the whole thing.

Players can buy in with Bitcoin and then cash out to Bitcoin any time.  Both processes are fully automated so I don't believe it's any slower or less convenient than sites where you bet directly with Bitcoin.

We can do a Bitcoin backed coin if players would prefer to have the value of their in-game coins fluctuate with the value of BTC rather than dollars.  Or do one backed by dollars and another backed by BTC and allow players to choose.


Yes, correct.


Not exactly.  This is a platform for a plurality of currencies.  The idea is that anyone can issue a new coin and then give it value by backing it with tangible sources of value.  In this case, I have $10k that I can personally put up to back this currency.  Putting an end date on the coin and requiring the backing dollars to be paid out avoids the situation where a stablecoin operator can use funds from the escrow because there is no clear obligation to repay.

If having USDB increase vs USD due to deflation from fees is too complicated, we could set betting fees to zero and maintain a strict $1 per buck peg.

There's no need for your casino to create a bitcoin backed coin because bitcoin itself suits as an accepted cryptocurrency for majority of the casinos. I understand that you're trying to save the value through this bucks you have which is just available on your exchange.

This is like buying an altcoin that has a utility for its own platform.

USDT, USDC, GUSD

The site seems to be interesting.
But as like other members,  i too didn't like the concept of Bitcoin as the Gambling coin.
Btc is widely accepted in many casinos and therby accepted by all.
According to me many players don't want to play with the site's default token.
The main reason for this is that,  the token hasn't been traded yet.
So OP hope you will consider all the suggestions soon.

I am confused, your statement is contradicting. Do you like their concept of using Buck as the currency for the platform or are you agreeing that bitcoin should be used?
I agree that, using their own stable coin could save the value of coin. The problem is, it is not tradeable in any other platform nor it is listed.
Which I think some gamblers would consider before playing their platform.

Great that you are honest and is willing to tell how much much money the casino has, but what will happen if the users win more money than the $10.000 the betting site is back with, does the site have additional funds to back up the business so it can provide security that everyone will be paid?

Why in the world would I invest in a coin that is not yet tradable in the market op? This is very risky since there is always a chance that your coin could fail which would lead to heavy losses for all the investors.

This is basically another form of gambling itself on top of gambling in your site. I suggest adding BTC as a payment option asap in order to attract more gamblers. If not, this is not the right board for this thread.

Agree the coin should just be Bitcoin backed. I think people who do crypto gambling just prefer Bitcoin for some reason.

Also,,, 1% house fee is this the same as 1% house edge? What do your odds compare to normal sportsbooks? In sports betting, people just care about the juice,,, if you have the lowest margins and you payout and settle with no issues, that is how you get people to bet with you, no other reason.

A house fee is where they cut a portion of your winning in a certain bet it's way far different from a house edge and Esports gambling site doesn't have a house edge.


I have been into Esport and just like a normal sportsbook, I think the odd varies on who are the competitors.

House fee on sportsbooks and house edge for casinos is similar in some ways because that's where most owners get their profits from. The small difference between them is house edge reduces the chances of winning and the payout while the house fee only reduces the payout.

Normal sportsbook that offers esports always have a high fee ranging from 3% to 6%. Having a 1% fee beats all sportsbook but one problem on polycash is that the supply is limited there's only a couple hundred bucks available for sale.

What is the advantages of your site to other online casino? I guest this is another normal sport book can you provide us some good feature of your esport site personally I like the cleanliness of your site but I dont understand how its really work.

My opinion is that their stable coins may have a future in gambling society and may be more advantages to other online casinos or sportsbook out there. I do agree with you about the cleanliness of their site and also have the same question as you as I am curious about their site and also I played Dota 2 game which they also have it in their site.

As I sell bucks, I will hold on to those deposits, so would have up to $20k in the business account if a majority of bucks were to be sold.  I am operating with no expenses because the important thing at this point is proving the concept, and I have another source of income.

This is parimutuel betting and all bets are between players.  There is no house holding onto funds.  When you place a bet, you actually destroy coins to one of your own addresses and then the protocol creates new coins to the winning addresses when each event pays out.  The 1% fee is paid to all coin holders via deflation rather than being kept by a house.

Parties holding onto the backing funds are a point of centralization but are not involved in the betting and should not be confused with the house in a traditional sportsbook.


This is a platform which makes it easy to create a currency and betting functionality is built in at the protocol level for these currencies.

In eSports Live $10k, "bucks" run on Litecoin and each bet creates a Litecoin transaction.  We could run on Bitcoin instead but TX fees would be $1-$2 per TX, compared to Litecoin where we can get transactions with 20+ bets confirmed for 0.0001 LTC = 1 penny.


We already have BTC payments & withdrawals built in.

There is some risk since this is a new app with lots of functionality.  But a lot of steps have been taken to make sure nothing goes wrong like holding backing funds in a traditional bank account and keeping only some BTC on public nodes and transferring the remainder to offline wallets.  We also have done comprehensive security reviews and did a bug bounty program for finding vulnerabilities and so are highly confident that the app is secure.

Even though this coin is not tradable on exchanges, you can still buy & sell your coins for BTC by trading with public nodes.

The advantages are:

• Low fees, and fees go to coin holders rather than a business owner.
• This is an open source P2P app which can you can install on your own computer.
• You can create your own betting currencies.
• By running your own node you can fork any coin where you disagree with consensus on the outcome of a betting event.
• This app has nice wallet and blockchain explorer features which you can use for viewing BTC/LTC data or managing your bitcoins/litecoins (or any other blockchain based on the Bitcoin code).
• This app does a great job of handling all the complexity of the blockchain and makes creating a new P2P betting currency as easy as integrating a data source or uploading a CSV file.

Has anyone tried placing a bet and willing to share their experience?

I think there no one on this forum did able to try the site and making a bet because at first,its never been an appealing thing if you don't really make bets directly with BTC.
You are still required to some conversion and I heavily agree on what said above that bitcoin is already capable on such manner.

Is the issue that no one wants to hold USD until their bet resolves, or that people are expecting to get ripped off on the conversion or something?

Based on the feedback here so far, I'm considering switching to a BTC pegged in-game currency called mBTC worth 1/1000 of a bitcoin each.  Deposits/withdrawals will no longer depend on the USD/BTC exchange rate so it will be easier to see that there's no deposit/withdrawal fees.  I want to make sure I understand your objection(s) first though.

Truly I have found this site very interesting to me. There are lots of arrangements to help provide the best experience of the user. I like the features of this site and the site's graphics design has been of good quality by visiting this site. There are also some interesting offers here which will attract people.

First time of hearing and seeing that there's this currency that runs on Litecoin. Because most of the tokens that were created on different platforms, if its not made of ethereum, it was made of EOS, TRX or Nano.

Why not just accept Litecoin directly instead of running it on with a name of 'bucks'?

Why would you really like to complicate things up? Just simply enable bitcoin deposits and let it do the job without boggling your mind.

I also don't know of any coins running on Litecoin. Maybe this is a first?

This is a protocol for colored coins.  This particular crypto asset is roughly pegged to the dollar hence the name "bucks" but uses trace amounts of litecoins to represent ownership.  Running on Bitcoin/Litecoin gives all the security and cryptographic functionality of those blockchains.  The colored coin protocol is needed for the decentralized betting functionality which relies on "burn addresses" where bets are placed by burning coins to your own address matching the format associated with the option that you're betting for.


Bitcoin deposits and withdrawals are already enabled.

Buying in, placing bets and withdrawing are pretty simple at the UI level.  If it seems complicated to you, I recommend trying the software.  I'm hoping to refine my presentation on how to explain this so that people can understand it easily.

If the house does not receive a but, what does it live off? Lost bets? And I find this concept of a cryptocurrency rather confusing. If it's a stable coin, the whole point of it is to be as stable as fiat while actually being crypto. What I am saying is that it's not supposed to rise or drop in terms of the price. You, on the other hand, say that this stable coin's supply is slowly destroyed, while the USD dollar backup remains. Where does this 'destroyed part' come from? I hope it's not people losing their coins, because of the system, right? And what's the point of making less of a coin that is growing in price (once it does)? I am not sure that the investors will find it appealing. Could you perhaps explain this part? I just never heard of anything like it.

Yes, I agree with you that instead of switching to bitcoin rather than adding or enable more cryptocurrency deposits would do the job smoothly and save some time in working to switch it to bitcoin. Enabling bitcoin deposits and other cryptocurrency is the same as switching to another cryptocurrency to use or pay for the game.

I don't know if that's the first because it's really the first of its kind that I've heard.

Yeah bitcoin's network is secured so that's why there's no problem of using it rather than other coins but you can't create your 'bucks' on its network. But if you really can create that with Litecoin, I'm not technically versed with it so it should be as you've said.

Money from lost bets goes to the winning players for each event rather than to a house.

As the one who issued the stablecoin and holds the $10k which is owed to the coin holders, the only way I make money is that until I sell them, I hold a large number of coins and so make money from the appreciation of those coins as fees reduce the coins in circulation.

But I see your point that having the coin slowly go up in price vs USD prevents it from being perfectly stable and is confusing.  There is a way I could change this so that fees go to the stablecoin operator rather than the coin holders.  This essentially makes the stablecoin operator into a house and so kind of goes against the original concept of creating a betting system with no house.  On the other hand this change gives the "house" a way to make money which helps make this into a sustainable business.  Betting still works without money being sent to a central party so this is still substantially more decentralized than a traditional betting system.
