Personally, I like backing a company that is based in Bitcoin. I believe that the value of Bitcoin will continue to rise.
It's not a company thats based in Bitcoins. It owns property, which is unrelated to Bitcoins. It should be fully invested and have no cash other than for contingencies, future investments etc.
If you want to bet on Bitcoin rising hold Bitcoins. This is Fiat investment (nothing wrong with that) that just happened to raise it's money through Bitcoins.
Pretty much the optimal point of this company would be to liquidate Bitcoin assets at higher prices and then buy back Bitcoins from rental revenues at lower prices at least I think that is how it should work.
