When the general public starts asking questions like that, I am more inclined to be on the sell side rather than the buy side. I'm going more with Warren Buffet on this ride up. Keep some dry powder cash.

But everybody has to ride their own ride.

I did get lucky on the tech ride way back when on memory storage chip companies. Got lucky and got out before the crash. Pure luck, no skill involved. If you guess right, a lot of money can be made or "won".
