Sometimes it seems that the owners of the exchanges forget that they are dealing with bitcoin. let's look at this:
Furthermore, if a “suspicious” account makes a transaction worth more than $2,000, all the corresponding information will be transmitted to law enforcement agencies.
1 BTC = $7700
there are people who own a lot of bitcoins, are investors who bought when the price was low or are miners... the fact is that 1 bitcoin has a price much higher than $2000. I wonder why $2000 instead of setting values too high?
In the US, financial institutions file
Suspicious Activity Reports above a $5,000 threshold. Many other countries have similar conditions required by AML statutes.
Sadly, there is now a renewed push from the powers that be towards lower reporting thresholds. For example,
the FATF travel rule -- which isn't actually law yet anywhere -- requires customer due diligence above $1,000.
Plus, compliance-minded exchanges like Coinbase will be erring on the side of caution and may implement lower internal thresholds than the law actually requires.
