I would say, never! Look where it is now, think about all the speculation people have put on coins, 1K here, 5K here, 10K here, 50K there, none of these predictions have come true at all - sure we hit 1K but that is the only real highpoint, no one has predicted any real hits since.
What, we didn't hit 10k in a month since hitting 1k? Wow of course you are right then, bitcoin is doomed! It has two days to be worth a million or it will never be! You are very smart!
