I'll be glad to update you once we go ahead with the process, but what machine we use is irrelevant to the question I outlined in my post.
- So, about the network difficulty, I understand it's a gradual thing, but 15% in 24h, does this mean in one week it won't be profitable anymore?
To give you an idea of the situation in USD, yesterday my forecasted monthly profit with 800TH/s was 71.5k$, today it's 60.7k$. And that's considering Bitcoin at 19.15k$ (it has actually gone down 1k$).
If network difficulty keeps going up at this rate or BTC goes slightly down, I won't even be able to recover the investment in months.
Cheers
Indeed, its not relevant, but what i said refer to very low chance of seeing any of the hardware at the expected date, hence vapor, for now. Moving on, difficulty jump;
It happens every 2016 blocks, target 1 block per ten minutes average and is based on effective network hashrate, 15% per day is inaccurate and impossible it would mean the whole world's mining operation tripled in 8 days.
So for explanation sake, if the whole world was using only and exactly 100 000 Antminer S9, and you online 10 000 more immediately after new diff change, and they remained at 110 000 S9's you would have a 10% ish difficulty increase over a bit under 2 weeks. Now scale that up to current massiveness of the whole network and that's how it works, but with many more actors.
So if you want to guesstimate growth, look at the past and forcast future deployments as best as you can.
