Fake ASIC miner shops: how to tell a real seller from a clone

You research the manufacturer, find the machine, land on a site with their logo and specs, and pay. It isn't them. Manufacturers publish lists of the clone domains — here's how to check.

The 2028 Bitcoin halving: what it actually does to your miner

The halving doesn't just halve your income — it halves your break-even electricity price. A miner that works at 12.2c/kWh today needs 6.1c after April 2028. Machine-by-machine numbers.
