FinCEN, via Bradley Stevens in 2011, told Bitcoin USA (now dissolved) that BTC is stored value [https://bitcointalk.org/index.php?topic=41155.0;all]. But even if the director of FinCEN had made an official statement about it, such statements are not legally binding, so they're only good for guidance. In addition, the Bitcoin community at large generally speculates that the government thinks Bitcoin is more likely to be covered as stored value rather than the other two money transmission subcategories (payment instruments and money received for transmission). It's a bold statement for the Foundation to say that Bitcoin is not stored value when the community has been guessing that our various governmental bodies thinks it is stored value (despite any nuanced differences in their definitions of stored value).
Did you read any of the posts above. It isn't a bold statement. FinCEN says in black and white that virtual currencies (to include Bitcoin) are NOT stored value. Period. End stop. There is absolutely no ambiguity about it.
Cited once again since it seems to be difficult for you to find it. Not FinCEN not longer uses the term "stored value" they use the more inclusive term "prepaid access".
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) .
