Marketplace — Physical Goods

The Marketplace board hosts sales of physical goods + non-service offerings paid in BTC. Hardware wallets, mining gear, books, art, collectibles, and the occasional unusual item. The principles for safe trades are nearly identical to general e-commerce, with three Bitcointalk-specific extras: escrow, trust, and crypto-payment dynamics.

Common listings

  • Mining hardware — ASICs, GPUs, PSUs (post-mining-cycle gear is common)
  • Hardware wallets — sealed and used; verify provenance carefully
  • Computers + tech
  • Crypto-related collectibles — physical Casascius coins, early-era memorabilia
  • Books + research material
  • Gift cards + digital codes — high-fraud category, extra caution

Safe seller protocol

For sellers:

  1. Create a clear listing thread with photos, condition, price, shipping policy
  2. Use a separate post per item if selling multiple
  3. State which escrow agents you'll accept
  4. Take tracked, insured shipping; document with photos
  5. Don't ship until escrow confirms deposit
  6. Maintain communication; respond within 24h to PMs

For buyers:

  1. Read the seller's trust history fully
  2. Verify the listing photos aren't stock photos (reverse image search)
  3. Insist on escrow for anything above ~$25
  4. Get tracking number before releasing escrow
  5. Inspect on arrival; if mismatched, open a dispute in trade thread

Specific hardware-wallet warning

Used hardware wallets from unknown sellers carry firmware tampering risk. A tampered device can leak your seed phrase to an attacker on first use.

Do

  • +Buy hardware wallets new from the manufacturer or authorized resellers
  • +If buying used, factory-reset + reflash firmware before use
  • +Verify the seal/packaging integrity
  • +Generate a fresh seed on the device, never accept a 'pre-generated' seed

Don't

  • −Use a hardware wallet pre-set up by anyone else
  • −Trust a 'sealed' device with broken or tampered packaging
  • −Type a recovery phrase into a device handed to you by a stranger

Gift cards + digital codes

This is the highest-fraud Marketplace category. Common scams:

  • Codes already redeemed before sale
  • Codes that work briefly then get clawed back
  • Codes traced to fraud → buyer's account flagged

If you must trade digital codes:

  • Use escrow with explicit "code must remain valid for 48 hours" terms
  • Verify the code before releasing escrow
  • Prefer larger denomination single-codes over bundles (easier to verify)

Disputes

Most marketplace disputes resolve via:

  1. Documentation in the trade thread (screenshots, tracking, shipping receipts)
  2. Escrow agent decision based on evidence
  3. Public trust feedback reflecting the outcome

Without escrow + documentation, disputes have no resolution path. The aggrieved party can only post in Reputation as a warning to others.
