Yeah, but every 2 weeks it will keep going Down, so say they deliver middle July, and its 10 dollars profit a day, and then 2 weeks later with everyone delivering soon, i am assuming it will go to 5 dollars a day, and then by mid august when most people are shipping their devices its pointless. Unless you just want to mine bitcoins for the fun of it, and hope that bitcoins goes to 1k a coin
, or store it at your work and don't have to pay power costsYou are projecting difficulty to double every month and price of BTC to remain unchanged. Neither of those is likely.

Plug in some numbers for the 64 and the 16 boards. Make sure you use the Expert mode to account for difficulty and deliver time. Try raising and lowering BTC price, difficulty and delivery time to get a sense of the variables involved. A few weeks delay can have dramatic effect on your ROI. It may make you reconsider how much you are willing to invest or risk with TerraHash.
Cheers!
Using this calc, an estimation of 1.8% increase per day in diff., one 4.5 board will never break even lol
