I will sell my Bitcoin when its price is back to $ 20,000.
Because this is the price when I bought and dropped its price. So now I still buy a lot of bitcoins so my profit is bigger when it comes back to its previous price
Why would you sell it on how much you bought your bitcoin? How can you earn profit on that way? If i were you i will be waiting for more until it reach to the amount that double the price or atleast 50% profits i can earn from my bitcoins.
Just read it carefully he said he will buy more bitcoins now and then he will sell it when the price reaches $20K again,this is also good strategy to be followed by more person to make profits when their crypto currency was crashed.But most of the people don't have guts to do that kind of thing they will sell their coins for lower price from their cost and get back again and buy at higher prices so they never can earn anything by doing this.
