FinCEN separates users from money transmitters by activity, not by branding
FinCEN's 2013 virtual currency guidance says a person who uses convertible virtual currency to purchase goods or services is a user and is not a money transmitter on that basis. By contrast, a person who accepts and transmits convertible virtual currency or sells created units to another person for real currency or its equivalent can fall into the money transmitter category.
The fact pattern matters more than the technology buzzword
FinCEN has repeated through rulings and enforcement that MSB status is activity-based. A company may call itself a wallet provider, marketplace, miner, or protocol service, but if it engages in money transmission services within the regulatory meaning, it can still have BSA obligations. The legal test follows the conduct.
Map acceptance and transmission before guessing at MSB status
A good FinCEN memo identifies whether the business receives value from one person and transmits value to another person or location, whether it is merely using digital assets for its own account, and whether an exclusion or narrower ruling applies. That activity map should exist before launch, not after enforcement interest appears.
Frequently Asked Questions
Is someone who buys crypto to pay for their own goods automatically an MSB?
No. FinCEN guidance says a user of virtual currency for their own purchases is not a money transmitter on that basis.
What kind of crypto activity most often triggers money transmitter risk?
Accepting value from one person and transmitting it to another person or location is the core activity FinCEN focuses on.
Why should startups write an MSB memo before launch?
Because FinCEN regulation depends on actual activity, and the safest time to classify that activity is before the platform starts operating.
