Mining has no magic margin: it buys electricity and sells it back as bitcoin. As long as your kWh costs more than what your machine extracts from it, every day widens the gap — and the network does not help. Difficulty keeps climbing, so the same machine produces less BTC every month while drawing exactly the same watts.
A European household tariff is a retail tariff: taxes, transmission, supplier margin. A professional miner pays wholesale electricity, often a fraction of that. That difference — and nothing else — decides whether a machine is profitable. It cannot be negotiated from a domestic socket.

Two real details in your favour when you open an account with a referral: +5% mining power on your first purchase (capped at 25 TH) and 1 month of VIP Platinum+, a tier that cuts maintenance fees and raises the yield on crypto you deposit. The code does not change your price.
Referral code, to type by hand before any purchase: CALCULMINAGE — conditions and method on the bonus page.

Nothing here is investment advice. Mining is an asset, not a guaranteed yield: difficulty rises, the BTC price can fall, hardware wears out. Only commit what you can afford to lose entirely. Some platforms are not available in every country — check before opening an account.
