BTC should be worth whatever the buyer/seller wants to trade them for.
I think that makes them more unstable then saying they're worth a fixed price.
As I said before.
(b*r)/(2500000-d) = (144004*50)/( 2500000- 1777774.4820015) = 9.9694622
That should be the current price, but it is slightly off

about $2 high.
