A man goes to the doctor:

— Doctor, I have a problem: I can't sleep at night!

— What happened? — asks the doctor.

— I keep thinking about Bitcoin, — replies the man. — Where is it going? Will it go up or down? Should I buy now or wait? Sell or hold?

The doctor thought for a moment and said:

— You know what? Just sell all your Bitcoins!

— What are you talking about! — exclaims the man. — Are you crazy? What if it goes up?!$BTC
