As crypto becomes more popular these tracking services will become the norm. 1000 is a low amount in crypto, but in fiat it sounds about right
in the USA, suspicious activity reports (SAR) can be triggered at $5k and currency transaction reports (CTR) are filed at $10k. so these constitute much lower thresholds than ever before. i sure hope this doesn't become the standard.
i can't imagine how/why they would spend resources to track such small amounts of money!
