Is it really a big mistake to sell portion of your bitcoin and then rebuy back when the price has dip?
In the case of long-term investment, I think this is completely wrong. Because Bitcoin is very volatile, when you sell and after some time if you want to buy, if the price of Bitcoin increases a lot in the meantime, then you will have to buy Bitcoin at a higher price. Again, suppose if you invest today at a price of $ 50 and if the price of Bitcoin decreases a lot and if you want to sell your investment and buy again, then you will have lost a lot of money.
The best way for an investor is to continue buying continuously. If a person buys depending on the price of Bitcoin, then it will never be the right decision, but a trader does so. So always depending on your discretionary income and adopting the DCA method and continuing to buy continuously will be the best decision.
