Unless bitcoin forks to a gpu algo (lol) or another ethereum hits, 2016-2017 levels of profitability are not coming back. There's also a ton of hardware now waiting on the sidelines to hash.
Also eth will go POS (soon
).
Pretty close to my thoughts.
Here is another way to look at it.
Bitmain was selling s9 for 3000 in dec 2017 when coins were 20000 and diff was 1.4
An s9 made 0.0024 btc a day and that was 48 dollars a day 3000/48 is about 60 day roi.
Now an s17 makes 0.0012 btc and that is 12 dollars a day. 3000/12 is about 250 day roi.
We are not close to December 2017.
Also 1 s9 burns 1300 watts
And 1 s17 burns 2225 watts.
Once you factor that in it is even worse then my 60 day to 250 day comparison.
More like 66 days if power is 8 cents for the s9 in 2017
And 414 days if power is 8 cents for the s17 in 2019
Basically gear is really over priced right now.
I’m have 110 kwatts running and 40 kwatts of idle power due to high priced gear.
We can go to 350-400 kwatts and we are not adding a transformer due to high priced gear.
Basically gear is 2x what it should be.
