This is is the old story:
JOE KENNEDY, a famous rich guy in his day, exited the stock market in timely fashion after a shoeshine boy gave him some stock tips. He figured that when the shoeshine boys have tips, the market is too popular for its own good, a theory also advanced by Bernard Baruch, another vested interest who described the scene before the big Crash:
"Taxi drivers told you what to buy. The shoeshine boy could give you a summary of the day's financial news as he worked with rag and polish. An old beggar who regularly patrolled the street in front of my office now gave me tips and, I suppose, spent the money I and others gave him in the market. My cook had a brokerage account and followed the ticker closely. Her paper profits were quickly blown away in the gale of 1929."
This is my story:
When bitcoin was at 17.000 USD, this truck driver friend comes to me, knowing I'm an ex-banker and says: "Man, I've heard China is making a new crypto, how can I get hold of it?...... "
So I said to myself: "Man, if this isn't a sign that one should sell, I don't know what is"
I wish I have passed this info to a couple of my friends. They've bought at 1.000 and they've both currnently have about 15.000 of profit each with a little bit of trading. Had I told them this story, they would have probably sold at almost the peak.
Again, history repeats itslef.
