Well, thats the idea that got me started 1 month ago, in the first place.

Setting up a farm of 10+ miners, ROI in X months, blah blah blah.

And up-to-date, I had accomplished only these few things : purchased pre-order M3 miners, a little bit of BTC in my online wallet, awaiting for my Nano S Ledger and pending account limit increase/verification from Xfers.

Very frustrating, I can tell you that. It has been a roller coaster ride since I left my last fulltime day-job and embark on this BTC adventure. Everything seems so feasible on theory, but its nuts in the real world.

Lastly, the cryptocompare calculator is incorrect on the diff count. Do not use that crap.
