@envion, thanks for fast replies.

Dragos Roua has some very interesting questions on his blog, could you pls. respond?
1) "shortly, Ethereum will move to Proof of Stake, so mining Ethereum will no longer be possible
2) Bitcoin mining infrastructure is already decades away in places like China or Iceland, where they plugged into solar plants, thermal water plants or river power plants, entire factories, not just pop-up units - that leaves very few profitable currencies that you can mine ..."

We are future proof. We are multi coin mining capable. That means we are capable of mining all 607 and more upcoming crypto currencies that are minable over time.

We support currencies based on these algorithms:  Ethash, CryptoNight and Equihash, as well as the important Blake algorithm which enables the ability to dual-mine two coins
simultaneously.

We are capable of many alt coins. Ethereum has only a market cap of around 15% so a switch to Casper PoS would not affect our profitability.
