Every miner on earth is playing the same game: make BTX for less than it sells for. This page gives you your number in 60 seconds. Add your machines below, we run the math at live network difficulty, you get two prices. That's it.
Every machine you run or plan to buy. Renting GPUs? Pick Rent and enter what you pay per GPU per hour. Bought the hardware? Pick Own and enter watts, your power price, and what the machine cost. Mix both. Your fleet saves in this browser and reprices at live difficulty every time you come back.
The part nobody shows you. The network grows, your hardware does not, so your daily BTX shrinks every week. That means your rig will only ever mine a FINITE number of coins. Sell some to cover costs, and the question becomes: can you mine them back before growth eats your share? Two inputs, straight answers.
Your spreadsheet says a sale at today’s price is profit. The treadmill disagrees. The coin you sell has to be replaced by mining on NEXT week’s network, and that replacement cost is your TMC from above. Sell Tax = your sale price − your TMC: what the market pays you against what replacing the coin costs you. Positive means the sale pays for its own replacement. Negative, in red, means the sale does not cover replacement and you shrank yourself. Blank sale price uses the live model; type your real OTC price and see what that discount actually does. It reprices live with your fleet, the measured growth, and your price.
Add machines and the growth rate above; your Sell Tax prints here.
