seems to be worth it so far!

Glad you think so, I am just starting to get my larger payments rolling through from genesis.

Genesis has 2 years contracts but they costs more, so in short period HashFlare should be more profitable (comparing ETH contracts)

You have a point Jack, save the money on shorter term contracts with ETHs crazy rise right now and get more profit, I get that for sure. I am thinking ETH will boom for a long time, so looking to get up to 50 at least MH/s by July on GM for 2 years and long run is looking good. I love everyones advice and strategy.

Also we should take in account Ethereum switching to PoS in some future, but not enough info atm. But i think it will be in 2018 so i talked about 1 year.
Genesis will switch ETH contract to another crypto in case of PoS, hashflare - i don't know.

Yeah GM would just switch it over and we would lose nothing, I am thinking building my ETH contracts and then just transfer out the ETH as full coins to my coinbase and then go with the flow once the eth contracts switch on GM.

I asked HashFlare support about it. They said that they will make official announce when will be more info about PoS and will switch to another crypto (like Genesis)

Yeah, same thing from GM, I don't think we would be at risk to lose anything but just a "credit" of contracts to go to another allocation.
