Yeah, Having your own coin greatly complicates the math of figuring it out. At the end of the day I think we can ignore the coin. Whenever the inflow of funds dries up, and reserves/savings are gone. It will fail real fast. There is no way of knowing if they are keeping money in USD or bitcoin. Bitcoin has been going up so much they could be doing really well. Because they only give you back the Dollar value you invested in the first place.
