Due to the fact that there are a lot of such people on the market now, the big players manipulate the market and force these people to sell when the coins are cheap and to buy when the coins are expensive.
therefore you must be able to resist your desire not to be easily tempted, so that you keep trying to hold your coin to a safe condition. You are more careful not to let go easily because it can make you regret. the market can still be stable and can rise again so you are in no hurry to sell it.
