Doesn't criterion 4, "Seller or redeemer of traveler's checks, money orders or stored value", pretty much fit the bill?
Our responses in this thread will be limited until the issue is resolved however FinCEN guidance in April 2013 clearly indicates no other category of MSB applies. It is important to understand state law and federal law don't necessarily have the same definitions even for terms with the same "name". Generally speaking the law will define a term and it has that meaning and only that meaning in the scope of that definition. As we indicated in the response at the federal level however FinCEN has provided guidance that Bitcoins are not stored value and virtual currency does not fall under the definition of "currency dealer or exchanger". FinCEN no longer uses the word "stored value" in regulations preferring instead the more inclusive "prepaid access" however some docs are still out of date so you may still see the older term. At the federal level the two terms can be considered synonymous.

A person's acceptance and/or transmission of convertible virtual currency cannot be characterized as providing or selling prepaid access because prepaid access is limited to real currencies. 18
Dealers in Foreign Exchange
A person must exchange the currency of two or more countries to be considered a dealer in foreign exchange.19 Virtual currency does not meet the criteria to be considered "currency" under the BSA, because it is not legal tender. Therefore, a person who accepts real currency in exchange for virtual currency, or vice versa, is not a dealer in foreign exchange under FinCEN's regulations.
