The real meat in this letter is under Section C for "stored value." The Bitcoin Foundation says that Bitcoin is not stored value. This directly contradicts U.S. Department of Treasury FinCEN statements which say that the reason why Bitcoin operators need money transmitter licenses (or MSB licenses) is because BTC is stored value.
Not sure where you got that idea. Stored value issuers are MSBs but stored value issuers are NOT money transmitter under federal law (SV issuer aka "prepaid access" is one type of MSB entity and MT is another).
FinCEN specifically said Bitcoin exchangers are MT because they accept Bitcoins which are "other value that substitutes for currency"
FinCEN also specifically said Bitcoin exchangers are NOT issuers of prepaid access (stored value) because those require "real currencies".
An administrator or exchanger that (1) accepts and transmits a convertible virtual currency or (2) buys or sells convertible virtual currency for any reason is a money transmitter under FinCEN's regulations, unless a limitation to or exemption from the definition applies to the person.10 FinCEN's regulations define the term "money transmitter" as a person that provides money transmission services, or any other person engaged in the transfer of funds. The term "money transmission services" means "the acceptance of currency, funds, or other value that substitutes for currency from one person and the transmission of currency, funds, or other value that substitutes for currency to another location or person by any means.
...
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
18 This is true even if the person holds the value accepted for a period of time before transmitting some or all of that value at the direction of the person from whom the value was originally accepted. FinCEN's regulations define "prepaid access" as "access to funds or the value of funds that have been paid in advance and can be retrieved or transferred at some point in the future through an electronic device or vehicle, such as a card, code, electronic serial number, mobile identification number, or personal identification number." 31 CFR § 1010.100(ww). Thus, "prepaid access" under FinCEN's regulations is limited to "access to funds or the value of funds." If FinCEN had intended prepaid access to cover funds denominated in a virtual currency or something else that substitutes for real currency, it would have used language in the definition of prepaid access like that in the definition of money transmission, which expressly includes the acceptance and transmission of "other value that substitutes for currency." 31 CFR § 1010.100(ff)(5)(i) .
