Opportunity In 2016 the market size of the online gambling industry was estimated to be $45 billion USD. These are impressive numbers. Let’s take a closer look at the cryptocurrency gambling market in particular. We will first focus our attention on Bitcoin, and then use this as a guide towards the future of gambling on Ethereum, the 2nd most popular cryptocurrency in the world. Bitcoin currently has a market cap of ~$15 billion USD. [1] It is estimated that 50-60% of all Bitcoin transactions relate to online gambling. [2] In the past year, Bitcoin and alt-coin casino revenue was 3,173,833 BTC with a profit of 15,173.6 BTC. In the same period, 20.83 billion bets have been placed across Bitcoin casinos. [3] Bitcoin is currently the largest cryptocurrency by market cap and as such, represents the largest share of the cryptocurrency gambling market. SatoshiDice launched its Bitcoin based dice game in 2012 and currently enjoys a lion share of the Bitcoin dice game market with 134,374 Bitcoin wagered last year alone. Enter Ethereum Ethereum is a disruptive technology that looks to change the way the world does business. The rise of Ethereum has been gargantuan in a very short time with some predicting its market cap will eventually be larger than that of Bitcoin. The current market cap of Ethereum is just under $1b at ~$965 million. [4] Released mid-2015 it is now the 2nd largest cryptocurrency by market cap. The popularity of Ethereum is soaring due to the programmable ability to run smart-contracts (auditable code) on the Blockchain. World banks, multi-national accounting firms, business solutions and application developers are looking at how to leverage this network to reduce the cost-of-business. Taking into consideration the recent rise in popularity of Bitcoin gambling and the benefits that Ethereum now offers players above and beyond Bitcoin (no sign-ups, no deposits, fully transparent betting, fully transparent code), Etheroll proposes tremendous opportunity for the traditional style of dice game to be ported over to the Ethereum protocol. Our platform provides this solution as a web-based, transparent and decentralized Ethereum dice gambling Ðapp. Players will be 100% confident Etheroll behaves in a provably-fair manner, thanks to the cryptographic nature of the Ethereum protocol and its underlying distributed ledger - the blockchain. Our smart-contract application layer runs entirely on the Ethereum blockchain, which means it is auditable, transparent and verifiable. Etheroll will accept wagers from players in units of Ether, via our unique web-based interface. The decentralized and immutable nature of our smart-contract layer ensures players will bet with 100% confidence their funds are not subject to the risk of hacks, theft, or misconduct by the Etheroll smart contract. This provides a level of auditability, accountability and transparency that is just not available to players of traditional gambling platforms. We are feeling confident about the future of Etheroll and its position within the gambling space on Ethereum for the considerable future. We will be a part of Ethereum gambling from the get-go. Will you?

Whitepaper A draft of the Etheroll whitepaper is available for review here (1.02MB)

Crowdfund We are inviting you to ‘bet on the house’. Fuel the crowdfund with Ether during our token creation phase, and you become the holder of ÐICE (ROL) tokens which grants you rights to all profits the house generates via our dice game, as well as the right to vote on proposals (new games/features/house edge). During the crowdfund, when our crowdfund adddress 0x805129C7144688224c122c924E3855D5b4FA01D8 receives Ether, ÐICE (ROL) tokens are sent directly to the sender. Each ÐICE token grants its owner the following rights and has the following characteristics: Direct earnings - Proportional to the number of tokens they hold. Token holders as a collective receive 100% of the profits generated by the house every 12 weeks. House profits are generated via the 1% house-edge. Tokens holders are exposed to each bet with the advantage of the 1% house-edge always being in their favor. The ÐICE token will be tradeable on popular exchanges. Voting rights – Token enable holders to vote on proposals. For example, lowering or raising the house edge, or, adding a new game to the suite. Important Details Start Date: The ÐICE (ROL) token creation phase begins at 10:00 UTC February 13th 2017 Duration: 14 days. Conversion schedule: Week 1: 1 Ether (Ξ) for 200 ÐICE (ROL) tokens Week 2: 1 Ether (Ξ) for 100 ÐICE (ROL) tokens # of tokens available: 25,000,000 Note: The founding team is pre-allocated a total of 2.5m. Any tokens that may remain unsold after the token creation phase will be destroyed to rule out any possibility of dilution. The crowdfund address: 0x805129C7144688224c122c924E3855D5b4FA01D8 Funds Allocation Hard costs are found primarily in paying winners, developers, marketing. Here is a breakdown of the allocation of Ether raised during the crowdfund. 80% of Ether created during the crowdfund will go directly to the bankroll which forms the house bank in order to pay winning bets and generate Ether via the 1% house edge. 20% of Ether created during the crowdfund will go directly to Etheroll for continued development of the ecosystem. Rewards Every 12 weeks the Etheroll smart contract will move any and all Ether earnt from the core game smart-contract to the ‘Rewards’ contract. From here token holders are able to draw down the Ether their tokens have earnt. 100% of all profits generated during each 12 week cycle is distributed to our valued token holders. Token holders as a collective receive 100% of all Ether the bankroll generates. Rewards are available to token holders on a recurring 12 week cycle. The amount of rewards available to each token holder is proportional to the amount of tokens they hold in relation to the total supply. For example, if you own 10% of all tokens, you would be allocated 10% of all the rewards available, in perpetuity. Expected Value The house bankroll is created from the Ether token holders have raised during the token creation phase. Each token holder is rewarded in Ether according to their percentage of the total house bankroll. Etheroll uses a 1% house edge and backers receive 100% of the house wins and/or losses. This means a 1% Expected Value (EV) that is shared by token holders. House protection Etheroll limits the maximum profit a player can make on a bet relative to the size of the bankroll. This means that if the house loses money to lucky players, the maximum allowed profit made on new bets will shrink. The automatic adjustments of the maximum allowed bet profit makes it difficult for players to win the entire bankroll, however, please be aware that there will be extreme variances and down days, but over the long run, the consistent 1% house edge should always work in the token holders favor. Potential Risks for Token Holders The house can't choose when to play; it just waits for players to place bets. If players stop betting, a house profit may never occur. Players can choose to stop at any time and if they stop when they have a profit, the house will remain with a loss.

You may struggle to recover your investment.

The house edge is only applied when paying winners (1%). There could be a huge variance in the up and down days for the bankroll. Over time, the expected value means Etheroll bankroll should continue to see a 1% increase in the total amount of Ether in the bankroll. If you have ever done any serious gambling, you will know what this means for the house in the long run.
