Warning: I just got on an elevator in New Orleans. There were two guys on the elevator. They were both talking about the stick market, and how they Keep putting money in it, and it keeps going up, and up.
I have seen that kind of conversation, by two complete strangers, twice before in my life.
The first time was about a week before the big crash in 1987.
The second time was back in the summer of 2008- a month before things went south.
I'm telling ya- there is your sign..... I just saw it on an elevator in New Orleans.
That is a good tell. Let me know if you hear anybody talking bitcoin.
