When the price of bitcoin was $17000, many people said that the price would not fall, then the price fell and I remember that at that time I panicked and sold at  $16000 and did something very good because the price fell a lot , the price dropped to $3100... sometimes panic and sell can be very beneficial, it can save you from a big loss. Of course later I learned to control my panic and today I do not panic. But it was a good decision to have sold us $16,000
