Here is a small simulation.
You pay 4000 $ for the hardware, that means about 8 BTC right now
If delivered in 2 months from now, it will give you back 2 BTC at best scenario with a 0.1$ kw/h price.

It's so sad when I see so many people getting scammed by these big companies Sad

Same goes for both SP30 and SP31.

Your simulation is absolutely useless because the future difficulty prediction has no basis in reality.

you must be very dumb.
even with a 14 % diff increase (which is very unlikely) you still won't make more than 3 BTC back out of the total of 8

My point is that the SP30 or SP31 will NEVER ROI, thus making the investment a big failure.
Can you prove that those will actually ROI ?
