I think technically Credit Suisse shareholders lose about half their value. They get 1 UBS share for 22 shares of Credit Suisse. 1 UBS is bout $18 and 1 Credit Suisse is about $2... but this is really only a short-term issue I'm sure.
I'd say 99% of BTC's price rise is to do with all this bank news and people fleeing to a different asset. The problem is, I don't think people realize just how manipulated BTC's price can be, I have exposure to BTC but I don't think it's a safe haven in the slightest.
BTC is definitely not a safe haven, however perhaps people with a little more cash are likely looking that other people will go into it too, so there is a fair amount of speculative potential.
