The investment in cryptocurrencies is a kind of gambling, which, as shown by previous years, sometimes pays off. The panic selling of cryptocurrencies at the time when the price begins to fall is often unreasonable and rash. It is worth to wait out the worse moment to gain later. It all depends on how long the investment is planned, because someone who can invest for a short time is forced to sell their BTC when the price falls to reduce the maximum losses.
Technically this is statement is true and can stand with itself. Fear has no place in crypto so be sure that you are brave enough before getting yourself involve in here. Remember that you are going to invest and getting what you want is not going easy to get. Bitcoin might be down sometimes so make sure that you are ready to accept the challenge.
