I have had a similar yet different experience. I have 60Mhs of ETH and i have seen my rate drop but that is due to more people mining ETH. That is clearly expected with mining. Even if you purchased your own rig it would be mining less now that it was a few weeks ago. As for daily profit.....my has gone down as well but that is due to the price of ETH dropping too, is your 30% figure based on ETH or $$$ amount ...with the upswing today my profit is going up....I am pretty sure this is the risk/benefit to mining.
I have planned to start cloud mining in Genesis for btc alone with 30th hash power. Will it good returns to me. If I have started with it. More over it shows 0.0003 btc for maintenance when ai tried to buy the hashpower.
Is it correct? Please confirm the information bros.
