New to Bitcoin mining? Here's how it worksThree steps, one minute. Expand to read the basics.
01

You buy mining hardware

Purchase Bitcoin miners (ASIC machines) that run 24/7 solving mathematical problems to secure the Bitcoin network.

02

Miners earn Bitcoin weekly

Your machines earn Bitcoin rewards based on their computational power. At current rates, expect ~8% annual yield. As hashprice and Bitcoin price rise, your returns increase while your expenses stay fixed, improving your breakeven and accelerating payback.

03

Dollar-cost average automatically

Instead of buying Bitcoin at today's price, mining spreads your investment over time. You accumulate BTC weekly regardless of price.

Why mining? Mining lets you accumulate Bitcoin at a discount to market prices while benefiting from potential price appreciation. It's a passive, automated DCA strategy.

Break-even BTC Price

Minimum BTC price to remain profitable

$37,017

At current hashprice ($41), BTC can drop to $37,017 before you hit breakeven. Below this, you'd need hashprice to rise to stay profitable.

7-Year Projection

Your hashrate is fixed; the network's grows and the subsidy halves in April 2028. Coins per year fall accordingly, and the machines switch off in any year they would mine at a loss. Scenarios show the BTC price path on top.

Lands in Year 2. Coins per PH halve from that date.

Hardware assumed to run 7 years. Coins per year = year-1 production ÷ (1 + network growth)^(year − 1), halved from April 2028. Electricity and insurance stay fixed per PH; a year is marked off when revenue would not cover them. Scenarios differ only in BTC price. Fees ignored. Not a guarantee of future performance.
