Any kind of transaction $10k or more triggers a currency transaction report (CTR) for review. Depending on what they see, it could turn into a Suspicious Activity Report (SAR). BUT, any amount just close enough to that $10k and not hitting it, triggers some manual review.
But who cares at the end of the day when you are banking with good intentions. I plan on creating many CTRs and SARs once this beast is released lol.
