We have just recently opened an account for a customer who is a bitcoin trader (our first). They have also opened up a second account, under a different business name with different EIN, which is an investment fund for those who want to purchase very large amounts of bitcoin. While we are currently looking into this, THEY (our customer) claim, per FinCEN, the secondary account/business is not considered a MSB. The only reasoning I can come up with is they are not actually receiving the bitcoin at the time, but the money is placed in the account to be used by the company to purchase future bitcoin? rlcarey, I'm having trouble understanding this as well. There seems to be more questions than actual answers. I'm contacting FinCEN today, and will let you know what answer(s) I receive.
