In our experience reviewing hundreds of mining deals, the most common losses come from bad hosting arrangements — not bad hardware or low BTC prices. A bad hosting deal can lose you your hardware, your hosting fees, and months of mining revenue simultaneously. This guide covers every red flag we have seen in practice.
Pricing Red Flags
Pricing below $0.05/kWh equivalent is suspicious in 2026. Commercial electricity cannot be profitably sold below cost, and at genuinely good hosting locations, rates cluster between $0.06-0.09/kWh all-in for air cooling. A provider quoting $0.04/kWh or $150/month flat fee for an S21 Pro either has extraordinary power costs (unlikely and unverifiable) or is structuring the arrangement to extract money elsewhere — through hidden fees, equipment seizure, or outright fraud.
Hidden fees that appear after signing. Setup fees, infrastructure fees, management fees, insurance fees, network fees — legitimate providers disclose all fees upfront. Any provider that presents a clean price quote and then adds fees after you have committed capital or shipped hardware is a red flag. Demand a fully itemized cost structure in writing before signing.
Prices that "depend on how many machines you commit to" without clear scaling terms. This is a common technique used to pressure you into a larger commitment before you have verified the provider.
Contract Red Flags
No exit clause. A contract with no mechanism for you to exit is a trap. Circumstances change — BTC price drops, your financial situation changes, the facility underperforms. You need a defined exit: what notice period is required, what happens to your machines, and whether there is an early termination fee (reasonable) or no exit at all (unacceptable).
Liability cap of zero or "hosting provider not responsible for equipment loss or damage." Equipment does get damaged — from power surges, cooling failures, fires, and theft. A legitimate hosting provider carries insurance and maintains reasonable liability for equipment in their care. A contract that eliminates all liability for your hardware is a serious red flag.
Jurisdiction clauses requiring disputes to be settled in a state or country where you have no practical access. A contract specifying arbitration in a distant jurisdiction makes it effectively impossible to pursue legitimate claims.
Auto-renewal clauses with no cancellation window. Some contracts auto-renew for another year if you don't cancel within a specific window (e.g., 30 days before expiry). This is not inherently fraudulent but requires attention — you can get locked into another term without realizing it.
Operational Red Flags
No physical address for the facility. Any legitimate mining facility has a physical address. If a hosting provider will not disclose their facility location (even generally — "Kentucky data center" without a specific address), that is a red flag. You are trusting them with $3,000-5,000 of hardware.
Inability to show you your machine online. Once your machine is deployed, you should be able to see its hash rate and uptime through your mining pool dashboard. If a provider cannot connect your machine to a pool in your name with your wallet address, something is wrong. Never accept a "trust us, it's running" arrangement without verifiable pool data.
Consistently below-spec hash rate reports. Your pool dashboard shows your average hash rate. If it is consistently 10-15% below your machine's rated spec, investigate. Some variance is normal, but systematic underperformance may indicate your machine is being throttled, misconfigured, or is mining to the provider's wallet rather than yours.
Slow or non-responsive communication. Good hosting providers respond to questions within 24-48 hours. If a provider takes days to respond before you've signed — or becomes unreachable after — that is a preview of what happens when something goes wrong.
Verification Checklist
- ☐ Request the physical facility address and verify it exists on Google Maps / Street View
- ☐ Ask for 2-3 references from existing customers and actually call them
- ☐ Search "[provider name] review" and "[provider name] scam" online
- ☐ Request a signed hosting agreement before any money or hardware is transferred
- ☐ Confirm the contract includes all fees, exit terms, liability provisions, and uptime SLA
- ☐ Confirm that your machine will be connected to a pool in your name with your wallet address
- ☐ Ask for photos or video of the facility before committing
What to Do If You Suspect a Problem
If you are mid-contract and your provider is underperforming, unresponsive, or showing red flags: document everything in writing (emails, not phone calls), review your contract exit terms, and request your machines back in writing. If hardware has been stolen or you suspect fraud, contact local law enforcement and consult a lawyer about your options. Unfortunately, cross-state and international recovery of hardware is difficult — prevention is the only reliable protection.
