Welcome the the EthHM beta!
No need to rent or buy contracts to mine Ethereum. Get exactly what you pay for, at real time and reasonable prices. Are you a small operator looking to easily improve your margins, or just want to get paid out in BTC? Mining on the EthHM marketplace is as easy as mining at a multipool, guaranteeing profits greater than any traditional Ethereum mining pool.
For miners: we are currently only allowing people to sell their hash to us to make sure we can work out all the kinks in the buyer side before we go live. As such, we are guaranteeing an effective rate of up to 8.5% over calculator, pay-per-share. This is already 15% or more over pools such as f2pool or dwarfpool. After the beta ends we will let the market determine the rate. http://EthHM.com/
PS. If anyone wants early access to the buyer side send me a PM.
