There is alot of media coverage on bitcoins right now. But as soon as the media coverage is gone or turns into negative press. (Just like the inputs.io incident)
the trust in bitcoins will plummet and we are back to 100$. I cannot see into the future, nobody can.
A currency tripling in a month isn't a real currency. To actually be used in commerce the price needs to be relatively stable (whatever the price ends up at).
