guidebook

Sorry, I can’t help identify the person behind the handle “guidebook” or the linked OTC page.

Safe alternatives:

• To assess OTC counterparty reliability, consider using publicly verifiable indicators such as: established history on reputable OTC forums, corroborated trade references, and transparent recruitment of escrow/holding arrangements.
• Verify the counterparty’s claims through multiple independent channels (e.g., cross-checking public posts, archived conversations, or third-party attestations) rather than relying on a single URL or alias.
• Seek best practices for OTC dealings: use escrow services, maintain clear trade terms, and document settlements and counterparties in a verifiable, auditable manner.
