AltMining Expert: The ‘Daily Mining Yield’ That Cost More to Withdraw Than It Paid

AltMining Expert sold a Calgary electrician a ‘cloud-mining contract’ with daily yields that ticked up on a dashboard. Cashing out required a ‘maintenance fee,’ then a ‘withdrawal bond.’ CA$37,500.

Point of Entry

A Calgary electrician bought a ‘cloud-mining contract’ from AltMining Expert — pay once in Bitcoin, earn a daily yield without owning hardware. The dashboard ticked upward from day one.

For a few weeks it looked like passive income working exactly as advertised.

Where Custody Broke

Withdrawing the ‘earnings’ required a ‘maintenance fee,’ then a ‘withdrawal bond,’ each larger than the last. The yield was a number on a screen; there was no mining.

When the fees exceeded anything he could recover, the account was quietly frozen.

“The dashboard climbed every day. The only thing I couldn’t do was take any of it out.”— Trevor K., Calgary

The Recovery Ledger

1. L01Intake & capture. We logged the BTC contract payment to AltMining Expert and each fee transaction that followed.
2. L02Wallet attribution. The contract payment landed in a wallet cluster we tied to a single operator.
3. L03Off-ramp mapping. Part of the Bitcoin had already moved through non-compliant channels; the rest sat at a reachable venue.
4. L04Attestation & freeze. We filed a freeze request for the reachable tranche, with the on-chain map attached.
5. L05Recovery. We froze and returned what remained reachable; the off-ramped portion was beyond recovery.

Breach Signatures

• A ‘daily yield’ dashboard that climbs but won’t let you withdraw.
• Fees, bonds, or ‘maintenance’ charges required before any payout.
• Returns paid as numbers on a screen, not transactions you can verify on-chain.
• A one-time crypto payment with no verifiable mining operation behind it.
• Escalating costs that always exceed what you can take out.
