Fast answer
An accuracy number without method is not evidence.
Before trusting a crypto signal accuracy claim, ask what counts as a completed call, how partial targets are counted, whether stopped trades and expired ideas are included, and whether costs, slippage, and open drawdown are visible.
If the provider cannot explain the calculation in plain language, keep the claim in a low-confidence bucket.
Claim audit
What a reviewable accuracy claim should include.
Sample size
Ten clean screenshots do not prove the same thing as a complete month of every call.
Period boundaries
The record should show start date, end date, market conditions, and whether old calls are still open.
Counting rules
Partial targets, break-even exits, no-fill calls, and manual closures need fixed rules before the count starts.
Source records
Original timestamps, edits, stop updates, and close notes matter more than a polished summary image.
Regulator lens
Performance information can be presented in many ways.
Investor.gov warns that performance claims can be calculated and presented differently, and that readers should understand what factors are included or left out. For signal rooms, missing fees, deleted losses, and selected periods can make an accuracy claim look cleaner than the underlying trade history.
Review standard
Accuracy should be attached to a full result sheet.
A serious provider should let a reviewer map every signal from original call to final status. Until the full trail is visible, treat accuracy language as a marketing claim rather than proof.
