When does a crypto exchange report you to authorities?

Answer

On regulated exchanges, identifying info "travels" with transfers above $1,000/€1,000 (the FATF Travel Rule). In the US, institutions file a report on cash activity over $10,000 and a suspicious-activity report (from $2,000 for crypto businesses), and US exchanges now report your trades to the IRS on Form 1099-DA.

WagerX Forensic Observation

Reporting is driven more by behaviour than by size. The headline numbers are the $1,000 Travel Rule, the $2,000 suspicious-activity threshold for crypto businesses (regulated as money services businesses), and the $10,000 cash report — but what actually triggers a review is structuring (splitting transfers to dodge a threshold — itself a crime), mixers, privacy coins, and transfers to flagged or sanctioned wallets.
