About

ProfitMine is a small project that builds free calculators for crypto traders and holders — profit, staking rewards, mining income and break-even prices. We started it because most tools either demanded an account or pulled in live data we did not control.

Our principle is simple: the math should run on your machine. You type the numbers, we show the result, and nothing leaves the page. That keeps the site private, fast and free to maintain.

We are not a broker, an exchange or an investment adviser. We publish formulas in plain language so you can check our work and trust your own inputs.
