When you're dealing with currencies not backed by anything, yeah, this is quite common. As crypto's are taken more seriously (Especially with the arrival of non-PoW currencies) i think prices will rise and thus stabilize as time goes on. Even better if there's some backing from the precious metal communities.
However, even a little bit of experience tells you that provided the drop is not caused by something serious - say, faulty code or an exploit in said code - no doubt ,the coin will bounce back. Most do.
These are but minor ripples in the ocean that is crypto. The problem is people let panic and fear effect their judgement far too much - they get preoccupied with the more immediate and obvious trivialities and don't broaden their view outward.
Well I will tell you one thing, if we don;t launch in September...
