Hydrominer project (https://www.hydrominer.org) uses H20 token that can be used for:
A. Mining contracts
B. Renting mining equipment (cloud mining)
C. Exchange for H3O token
So far H2O token is available on COSS and on ETHERDELTA exchanges. The price for the token is quite different from day to day (e.g today from 0.00240014 ETH per 1 H2O up to 0.00500000 ETH per 1 H2O). My estimate is that the volume is quite low. Here is the link for COSS: https://exchange.coss.io/exchange/h2o-eth
A. Mining contracts
H2O token can be excanged for mining contract (Ethereum, Bitcoin, Bitcoin Cash, Ethereum Classic)
Prices are as follows:
1 H2O TOKEN = 12.5 KWH / 2 YEARS = 0.7125 WH
COIN MINIMUM PAYOUT AVAILABLE DAILY PAYOUT PER 1 H2O DAILY PAYOUT (USD)
Ethereum 0.01 ETH 3158 H2O 0.000007943891 ETH 0.00667745 USD
Bitcoin 0.02 BTC 179617 H2O 0.000000340702 BTC 0.00337136 USD
Bitcoin Cash 0.001 BCH 184897 H2O 0.000002755901 BCH 0.00332006 USD
Ethereum Classic 1 ETC 13904 H2O 0.000226581448 ETC 0.00883935 USD
ZCash 0.1 ZEC 12532 H2O 0.000013901810 ZEC 0.00541616 USD
According to my calculation the return is quite low considering the current price of the H2O token. At current prices 1000 H2O tokens cost around 2.4 ETH. Given the fact that you have to pay the tax for the service (this is charged on the invoice and your net token amount is reduced) you have around 833 H2O tokens.
According to data provided by Hydrominer 2 years of income would give the following result:
833H2O x 0.000007943891 ETH (DAILY PAYOUT PER 1 H2O) x 730 (number of days of the contract – 2 years) = 4.83060067819 ETH.
This allows for aprx. 100% profit in 2 years (from the point of crypto currency - USD prices might be higher or lower). Compared to Genesis mining etc. this is not as profitable as one might expect.
B. Mining equipment (cloud mining)
The H2O token can also be used to rent mining equipment (for 2 years) from their shop at https://www.hydrominer.org/online-shop/. Some of equipment is used/refurbished (like S9 etc.), some is new (but not all is in stock all the time).
When choosing this contract you are supplied with fixed supply of energy and you are entitled 100% of the profits. They promise that the cloud mining contracts start to mine within 24 hours after receipt of the payment and 100% of the mining income belongs to the customer (no other costs and fees will be deducted).
C. Exchange for H3O token
Another option for H2O tokens is conversion to H3O token (and later into a share). H2O token holders will be able to change their H2O tokens into H3O tokens after the capital market prospectus for the H3O token will be approved by the financial authorities (Q2 of 2018). How this will all work out it is not quite clear. They promise that more information will be released as soon as this will happen.
Conclusion:
I must say that I had bigger expectations for Hydrominer. H2O tokens have a lot of potential. But at current prices of the H2O tokens and of the currencies that are mined, I am not convinced that mining contracts are worth the investment. I haven’t made calculation about cloud mining potential, so I can’t give a detailed review about this. The same goes for H3O token.
I hope this helps, if you are researching this project.
