We seem way too early in our adoption level (still likely less than 1% of the world's population) to be proclaiming that bitcoin is becoming mature enough to no longer have severe FOMO episodes.
That depends on your definition of severe, of course. I may just be being over-hopeful but it seems that the long winter where we trundled along in the low-hundreds with the occasional hopeful sign quickly pummeled even lower may not repeat itself that badly. Then again, I felt the other way about six months ago but was proven wrong. Have to adapt to the circumstances, however (though the underlying truth that Bitcoin is currently cheap still applies).
