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.

7-Year Projection

Your hashrate is fixed. The subsidy halves in April 2028, so coins per year halve from that date. Scenarios differ only in the Bitcoin price path.

Your hashrate

Fixed for all seven years

Electricity and insurance fixed per PH. Any year below breakeven pays you zero, not less: Gasbox carries the shortfall under the agreement.

Halving

April 2028

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

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