In short
Mining economics rests on four factors: the price of electricity, the cost and lifespan of the hardware, network difficulty, and the price of the coin being earned. None of them is under the operator's control, and they move at the same time. This article explains the factors only; it gives no figures or projections.
Key points
- Electricity is the dominant recurring cost
- Hardware cost must be read alongside rapid generational turnover
- Difficulty rises as participants join, thinning each share
- All four factors move together and cannot be forecast
Definition
The main variables that shape mining economics: electricity price, hardware acquisition cost and depreciation, network difficulty, and the market price of the coin earned.
Electricity accrues for as long as the machines run, and its unit price varies enormously by region and contract. That is why identical hardware faces completely different conditions depending on where it sits. Cooling power and facility costs effectively add to the same line.
Hardware cost is fixed at purchase, but how fast that value erodes depends on generational turnover. New models push older ones down the ranking, and failures and power-supply replacements follow. An estimate made at installation will not hold for long.
Network difficulty rises automatically as more participants join. Even with unchanged hardware, a growing network thins your share. On top of that, the coin received fluctuates in price, so a cost base fixed in yen does not translate into a fixed receipt.
Of the four, an operator chooses only the site and the hardware. Difficulty and price are set outside and neither can be predicted. Any calculation that begins 'if current conditions hold' stops meaning anything the moment they do not.
Watch out for
- · Any pitch guaranteeing profitability or a fixed return misstates how mining works
- · With cloud mining contracts, users often cannot verify that the hardware exists or runs
- · Coins obtained by mining carry tax consequences in Japan, so keep records from the moment of receipt
