I don't think so that there is any time to get panic in any case of bitcoins. As bitcoins allow their users transaction free from fees and many more benefits.  While people's have made a habit of holding bitcoins. As the reason for falling of bitcoins is that the price of bitcoin is now below mining cost for a lot of mines.  Once you have mines close down, they tend to unload their stored bitcoin, which causes a chain reaction.  My sense is as of 1/19, that chain reaction is over and prices have stablized.

Personally, I think that the future of bitcoin is very bright.  However, that does *NOT* mean that the price of bitcoin will go up or down.  Bitcoin is a very useful medium for exchange, and I think that people should invest in companies that use bitcoin, but *NOT* in bitcoin itself. So there is nothing to be panicked.
