On one side, calculators with real numbers: prices, fees, power costs, 85 machines compared. On the other, a mining farm you build in the browser without risking a cent.
Live from the network, every 60 seconds
All without signing in, all worked out in your browser.
Your device measures its own hashpower and mines along. That becomes a farm.
Cart, Vein, Crusher, Shaft and Backfill. Every round earns something that flows into your farm.
Opens straight away. No account, nothing to install.
Bitcoin, mining, fees, wallets and the usual scams from the ground up. Short modules, with explained questions after every section. The basics cost nothing.
Learning
Numbers you can check, rather than opinions.
Two things under one roof. First, a set of calculators with real numbers: current prices, transaction fees, power costs by country and 85 miner models compared. Second, a game in which you build a mining farm without putting money in.
No. There is no sign-up, no account and nothing to pay. What you earn in the game is a number in your browser, not money.
No, and that is deliberate. Anyone promising you returns without a stake has something else in mind. Here you learn what the arithmetic looks like, and the calculators show what real mining would cost.
In your browser storage. Watchlist, holdings, address list and game progress go nowhere. There is no account for them to be written into.
Prices from CoinGecko, with Binance in reserve. Blocks, fees and hashrate from mempool.space. Power prices from Eurostat data, machine figures from manufacturer specifications. Every page names its source at the bottom.
