I get what you're saying, but then why even sell shares for Bitcoins?  You either are in a Bitcoin related business or you aren't.  If you aren't, you shouldn't be dealing in the coins period.  As the entire thing is up and down even in the process of buying and selling shares.  Bitcoin is part of the equation of this business until Branny decides to take it out of Bitcoin and put it into Fiat only.  Personally, I like backing a company that is based in Bitcoin.  I believe that the value of Bitcoin will continue to rise.  We're dealing with some China nonsense and a lot of speculation that will subside after this new fall over the PBOC.  You just need one country to latch onto Bitcoin and we'll be up into the thousands per coin.  This things can happen fast.  Don't get hung up on the bad news.  If you don't want to invest in Bitcoin businesses, there's a whole world of things you can invest in with Fiat.
