not to worry though, the potential of bitcoin has not gone anywhere. it is till there and still strong.
a drop after a huge rise is perfectly normal. but also a huge drop is not normal at all, and that's what's happening right now.
that is why i don't consider anything about the recent drop from $19666 down to $5920 (-69.8%) (prices from BitStamp) normal. it was an over-panic situation in my opinion where things got out of hand and the drop became a lot bigger than it should have been under normal circumstances.
