Buy the coin or build a rig: an honest comparison
The classic miners' debate: for the same money — buy the coin directly, or build a rig and mine it? The debate has no universal answer because you are buying different things. Let's lay out what you actually get in each case, count honestly, and see who each option suits.
The short version (for the no-time-to-read)
- The coin is a pure bet on price. The rig is the same bet plus cash flow, minus expenses, plus the resale value of the hardware.
- The rig has a cushion the coin lacks: hardware sells even if the price crashes. The coin has no cushion.
- The coin has liquidity the rig lacks: exit the position in a minute, no listings, no shipping hardware.
- The rig pays daily but demands electricity, space and attention. The coin demands nothing — and pays nothing until you sell.
- The decider is arithmetic at your tariff, not somebody else's payback charts from the internet.
What you actually buy
Buying the coin gets you exactly one thing: exposure to its price. It doubles — you double. It halves — you lose half. No interim payouts, no cushion.
Buying a rig gets you a composite asset of four parts:
- cash flow — daily coins you can hoard or sell;
- residual hardware value — cards sell on the second-hand market for years; even a "worked-out" rig returns a visible share of the investment;
- flexibility — the coin can be switched; a rig is not married to one algorithm;
- expenses and work — electricity every day, space, noise, maintenance.
Honest arithmetic
A hypothetical. A rig costing 3,000 units earns 10 units a day gross. Electricity at $0.07/kWh eats about a third — roughly 6.5 units a day net, about 200 a month. Simple payback is 15 months, and afterwards you still hold hardware worth half its price.
The same 3,000 in the coin: you hold the coin. If the price doubles in 15 months — the coin beat the rig. If it went sideways — the rig paid back through cash flow while the coin paid nothing. If it halved — the rig returned part through cash flow and returns more as hardware, while the coin is a straight minus 50%.
The conclusion is not "rig wins" but "rig and coin behave differently across scenarios". The coin wins in a strong rally; the rig wins in flat markets and moderate declines. The rig's disaster is a price crash plus rising difficulty (why coin revenue is not a constant) plus an expensive tariff. The coin's disaster is simply a price crash.
Run your own numbers: profitability formulas and the calculator with your tariff.
Who each option suits
- The coin — if you have no space, no cheap tariff and no desire to fiddle with hardware; if you need minute-level liquidity; if the sum is small.
- The rig — if the tariff is low, the space exists, your hands are handy and you enjoy the process itself. Bonus: the skill and the hardware stay with you into the next cycle.
- A hybrid is a legitimate answer: the rig for cash flow, part of the mined coins hoarded as a "coin position", part sold for expenses.
Where automation fits
A rig's main hidden expense is downtime and manual fiddling: they eat the cash flow that lets a rig beat the coin. OCBot tunes a stable overclock per card, handles failures by itself and brings the rig back without your involvement — in other words, it defends exactly the part of the equation a rig is bought for.
