When the market is bullish, everyone sits down and relaxes, watching their asset value grow. Easy
When the market is bearish, some people panic sell. Some are even losing money by selling lower than they bought (or for miners, less than what they paid for to mine it, TCO-wise). Some are holding but quite pissing their pants. Most are hoping that "someone do something". The legal matter regarding exchanges are getting a lot of focus, obviously.
Some developers are willing to (finally) give Bitcoin a true economical value, and it doesn't have to be in the form of a classic exchange. We have exchanges already, we just want them to be more solid, or we want more solid ones (and remove the GoxSPoF™).
These developers are currently (still) sitting down, and coding. Many Great Things, Bitcoin-powered, are definitely going to happen in the following years, even months.
I'm not saying that USD/BTC is going to stay up again in the short term, I'm just staying that as long as your are not really in need of the money that you have stored in bitcoins, the
safest bet you could make at this point is *holding*, even if the upward trend doesn't last in the near future.
Just my thought for comments
Cheers.
