The short concluding parts:
Following the “herd,” has always ended badly for investors. In every full-market cycle, there is an inevitable belief “this time is different” for one reason or another.
It isn’t. It has never been. And this time will not be different either.
However, what has always separated out the great investors from everyone else, is they have acted independently of the “herd.” They have a discipline, a strategy and a driving will to succeed.
They don’t “buy and hold.” They buy cheap and sell expensive. They avoid losses at all costs and they deeply understand the relationship of risk to reward.
They are the “non-stupid.”
These are the ones you want to follow.
Not the ones screaming at you on altcoinstalks telling you to “buy, buy, buy.”
