1.Country Tokens

Each country participating in the world cup has a unique token. Each country token has a selling price, which is the cost of the token. Any user who wants to purchase a country token will need to pay some ether ? selling price of the country token. When a country token is purchased, half of the profit is given to the previous owner and other half goes to the jackpot. Every time a token is sold its selling price increases.

Match Betting

Bettings is more conventional, where user bets on a certain team to win. All the world cup matches are available for betting. Once the match is completed the user can claim the amount they won if a bet was placed on the winning side. If the match is a draw user gets back complete bet amount.

Point of failure is painfully obvious. No player wants to try for the jackpot knowing that 20% goes to the site owner. It's far too high in an industry that considers even 10% normally taken by centralised gaming companies as "unfair".

What's the point of a trustless system if you have to lose so much of the cut? And what's stopping the devs from just buying those tokens back, knowing that 20% goes to them anyway?

This quite risky. What guarantees does one have to get back his tokens in the event of a won or drawn match? I do not think putting my money in a relatively new site created out of the excitement of the Upcoming world cup and without any form of escrow is good idea. You'll have to come up with something better to convince me!

Hi kevoh,
    Country tokens are safe from draws in fact they are not dependent on individual match outcomes. Users who own a country token, get their share of ether after the world cup is finished. For example say a user has token "Spain". After the world cup the result is as follows, say "Spain" lost in the final. So its place will be second. So second position gets 5 % share of the jackpot. Similarly every country will be in a certain position, and hence get a share of the ether. The table is defined in our main page.

When a token brought, the last user gets whatever the token cost + 50 % of the profit. Say for example A owns "Brazil" for 5 ether. Now If B buys "Brazil" for 7 ether. A gets 6 ether(thats 1 ether in profit). Whenever the last token is brought, the last user benefits.
