This is not a troll, but some data for the irrational exuberance in here.
A prudent investor would wait for a full reversal signal, like bitcoin, like darkcoin. Look at these charts and tell me why its different this time. Remember, even bitcoin is not "a new paradigm", yet. And before you tell me this is just the first sell off, are you willing to handle a 50% loss, hoping for the next run up, months from now?
