to be honest i would say that if the price reached $20,000 i would sell and expect to see a 10% drop to buy again, but this will also depend on the support that will have when the price reaches $20,000 and the economic conditions that will have when the price reaches $20,000, for example: there may be a case of having excellent news when the price reaches 20,000 $ in this scenario I will not run to sell
