Bitcoin prices fall not because of panic, more to profit-taking from traders, it is quite normal if you know the stock market. And usually it only happens for a while, it will not take long
Yes because nothing fundamentally changed with bitcoin. I fully expect price recovery or at least stability in the coming days and weeks.
There may be no fundamental changes within Bitcoin but there can be changes outside of Bitcoin that can have a pretty significant impact on the value of it, for a long time potentially, as well. The collapse in value we saw was (mostly) caused by a law passed in congress, and while it changed nothing with the blockchain itself, it had a large impact on Bitcoin market-wise and it's recovered about $300-$400 from it's lowest point, while still being $200 below where it used to be at.
