Avoid These Mining Mistakes
Most mining losses are preventable. These are the six mistakes we see most often.
New-gen ASICs depreciate 40-60% in the first 12 months. Used hardware at the right price often delivers better ROI than new hardware at inflated retail.
A 1¢/kWh difference in electricity cost changes your annual profit by ~$260 per machine. At 10 miners, that's $2,600/year. Always get the exact rate in writing.
A 12-month hosting contract with no exit clause locks you in through price swings, difficulty spikes, and facility problems. Always negotiate an exit or buyout provision.
If you don't know your hardware breakeven price, you can't manage risk. Run our calculator before every purchase to know exactly where you stand.
Bitcoin network difficulty grows ~20% per year in bull markets. A deal that looks great today looks marginal in 12 months. Always stress-test at +20% difficulty.
Hosting providers routinely overstate uptime, understate fees, and use vague contract language. Get everything in writing and use a provider with a verifiable track record.
