How Long Should You Keep Crypto Scam Evidence and Transaction Records?
Practical guidance on preserving cryptocurrency scam evidence, transaction records, communications and investigation documents for future reference.
# Keep original transaction information
Do not discard transaction hashes or wallet addresses after making a report.
Future investigative activity may depend on the original blockchain references.
Preserve communications
Keep relevant emails, messages, invoices and website information.
Keep exchange records
Save support tickets, account notifications, withdrawal confirmations and case numbers.
Maintain a timeline
Keep the chronology of events together with the underlying evidence.
Protect the evidence
Store records securely and restrict access to people who are authorized to review them.
Follow applicable retention requirements
If the evidence is connected with a business, legal case, insurance matter or regulatory process, follow the applicable retention requirements and advice of the relevant professional.
Avoid editing originals
If you need to make notes, keep them separately rather than replacing the original evidence.
Final thoughts
Cryptocurrency investigations can develop over time, so preserving the original evidence is important.
