Made some research on masternodes.online. This coin seems to be one of the most stable and meaningful.
Made a hyperbolic approximation to the last 27 days ROI data from masternodes.online.
The next 30 days will result in 50% ROI, days 30-60 - 34% ROI. Experimental data + next 60 days extrapolation looks like this:
MN population growth seems to be pretty linear so far:
In 30 days ROI will get to 670, in 60 to 445%. Those are very good numbers given that the price stays as stable as it used to be:
Most of other coins decrease in price rapidly, so their high ROI makes no sense.
By the way, what's the estimated return in medic coins when running GeForce GTX 1050 and intel i7-7700 @ 4 GHz?
