That was misstated by me. 20 months was the time to earn back your investment, not to fill the node. That’s roughly 34 months as I had already mentioned later in the post. This is based on my earnings calculator which was recently updated to reflect the latest network behavior. I corrected my original post.
The rest of the numbers I mentioned were correct. You make a lot of money on that HDD before those 5 years are up. Since I actually bought one recently, trust me, I did the math.
I stated my calculation. If it’s full after 34 months you use way more than half of the HDD in 5 years on average. Also… Why should I care if the ROI is 500%? Over those 5 years?
