How is $20 looking less and less likely again?
So BTCs drop quite a bit over the past 2-3 days - there isn't any reason why it wouldnt go back up soon. The "crash" (if you can easily call it that) is a result of a few things, at least what I gather, including the MyBitcoins scam and the fact that BTCs hit $20 so fast at first for example. The MyBitcoins scam was an immediate and one time occurrence that'll balance out very shortly.

To say that it won't go back to $20 for a long time is a bit of a long stretch.
To say that it'll NEVER go back to $20 again is an even longer stretch.
