I had to do a cost analysis for setting up a new bitcoin farm this morning. This is my breakdown
"This is the link for the miner
Cost to buy right now is £7999, but changes regularly. Price of Bitcoin is $29000 (£23010). At 104TH/s, this will mine 0.1616 bitcoin per year at the current difficulty.
As electricity prices increase, many miners will have to switch off, reducing difficulty, and increasing yield.
I cannot advise on future price expectations, but I can say that I mine and stockpile Bitcoin for a rainy day.
The ROI on this particular miner at the current price is 773 days.
At the all-time-high last November ($68990/£54732), it would have had an ROI of 330 days.
These are based on free electricity. If I based it on the UK national average of 19p/KWh, then the electricity will cost £0.19 x 24 hours x 3.068 Kilowatts, or a total per day of £13.99. Already, that would mean that most of the UK could not mine profitably at the moment. That will only get worse, making those with very cheap/free electric end up in a very good position.
There are two issues with these industrial miners. Heat and noise. They are as loud as being in a server room, and put out as much heat as a 3 bar fire, so must be ventilated.
It can be set to mine to a wallet on your phone, and services like bitrefill.com are a great way to get digital gift cards, and never be on anyone’s radar.
Centralised exchanges are terrible, as they want to know all about you."
