Usa is selling seized Bitcoins money and converting it back to usd, this shows they are interested in the coin and will be happy to allow price hikes happen cause they'll profit a lot from sales. I feel usa shall sooner or later back Bitcoins indirectly.
While a Japanese company has decided to pay part salary in Bitcoins, now how many of us wish we're part of that company don't we? Their motto to spread Bitcoins and gain more knowledge on its working that's good right for the crypto king.
A friend of mine recently said it the US Government is one of the largest holders of bitcoins and they didn't buy a single one of them but seized them all. No wonder they haven't and are never going to ban bitcoins ever.
