There is no missing out though. There is buying when it's lower and selling when it's higher and you can do that starting now as you always could. Or buy and hold if you think that's what you should do or whatever.
I really have no dog in the fight and don't really care one way or another. Just for the sake of the argument though: something can be complete shit with no redeeming qualities. It is not a must that it's good but imperfect and that it requires a solution to make it better. So the opinions of "no-coiners" are not inferior by default. You have to actually prove that they are with some form of argument or evidence.
