Guys, bubbles are a bad think expect for a hand full of speculators. A bubble means there will be a crash afterwards, that hurts the legitimacy of Bitcoin.
How about a steady and real growth instead?
How about long dry spells with a few unpredicted and random bubbles instead?
Steady growth on a log chart looks somewhat exponential, and not everyone views Bitcoin the same way, so bubbles will happen, it is part of the distribution mechanism, and so is the random time between them (or lack of a guaranteed bubble), even a steady decline helps distribute the coins, this is what allows Bitcoin to grow, embrace volatility it will add value to the few coins you manage save.
The love for tulips was propagated by a bubble, they can't be all bad, see tulips are everywhere now.
