What is HydroMiner?

The new platform plans to start up a mining facility that uses electricity from hydro power stations that will be based in the Alps. They state in their whitepaper that they can generate electricity using this method that will be 85% cheaper than the average cost of electric in Europe.
They also plan to use the water to help to cool their mining equipment which will mean that they're able to compete with energy prices in China.
Once the ICO is complete the new platform will offer mining contracts similar to how genesis mining operates. The tokens sold during the ICO will act as vouchers for mining contracts or can be exchanged when they're listed on a cryptocurrency exchange.
Unlike many recent ICOs, Hydrominer has already started their operation. They recently rented 2 hydro electric power stations in Austria, with an option to buy them in the future.
The funds raised from their token sale will be used to scale up their operation quicker.

What is cryptocurrency mining?

Without mining there would be no cryptocurrency. Mining involves using solving mathmatical equations which confirm all transactions on the blockchain. In return for mining a miner receives payment in that crypcurrencies coin or token relative to the amount of power they're using to mine.

How did Hydrominer get started?

In 2014 2 friends started mining cryptocurrency, they quickly realized that they were on to something profitable and soon their friends wanted to invest.
After a while they reached the maximum allowance of electricity that they were allowed to use. With mining gaining in popularity the pair quickly realized that the future of mining profitability would depend upon the power costs that the miner had to pay.
They started to look into cheaper electricity options and decided upon using a hydro power station. They then rented one of the power stations in Vienna which gave them the cheap electric that they needed. After receiving more investment from friends they've quickly to renting 2 power stations already.

The future of mining

In the near future it's likely that many home based miners won't be able to make profit by mining, quickly those in countries with high power costs won't be able to mine effectively, as the mining technology slows down the energy costs will become more of a factor.
It's likely that mining will become a specialized industry with investors investing into large companies rather than mining themselves.
In the last few months ETH has been one of the best cryptocurrencies to mine as the price has quickly risen to $300 and it can easily be mined with GPUs which can also be set up to mine the most profitable currency at any given time.

Current cloud mining market

A few major cloud mining companies have started in the last few years. The main problem with some of these is that they charge on the hash rate for sale, this can sound attractive to investors in the beginning as they sound very profitable, however as the network difficulty increases these contracts quickly become unprofitable.
Hydrominer plans to offer cloud mining contracts that will be based on the cost for each kwH, with the profits of each kw being paid out to investors.

Profitability

Hydrominer state that the average cost to fill a container with GPUs works out to be $500,000. Once set up each container will produce around $50,000 per month in revenue, the cost of electricity and service would be $10,000 with an extra $15,000 saved to replace hardware. This leaves a monthly profitability of $25,000 per unit.
If a mining contract was purchased today at a cost of 1,000 H20 (10 ETH) for a term of 24 months it would offer a return of just over $6,000, this results in a good profit for investors.

ICO Details

The purpose of the ICO is for the project to raise additional funds to scale up their business. The new H20 token will be used as a currency for ordering mining contracts.

• Type of token: ERC20.
• Total supply: 100,000,000
• Price: 0.01 ETH.
• Hardcap: 25,000,000.
• Currency accepted: ETH.

Conclusion

This is the most transparent ICO I've ever seen. They offer details of their location, profit projections, history and full team. It's unlikely that the price of this token will rise sharply as it's value will be tied to the mining contracts. However it offers a great long term investment for mining.
The ICO also offers the advantage of the team having already set up a successful business, many of the current ICOs don't even have a working concept yet.
