the "currency sector" and mostly banks are celebrating these days. with the huge trading volume that bitcoin is attracting, millions of dollars is going through banks. processing all these transactions is giving them a lot of revenue that never existed before.
not to mention all the money they make by trading bitcoin (remember JP Morgan investment in bitcoin)
It is said that some people mortgage their own house loans have hoarding Bitcoin,
"some people" mortgage their house to do a lot of weird stuff. it has nothing to do with bitcoin. it is them. if it weren't bitcoin they would have done something else with it.
