so when the price is bear we have to use this opportunity so that we can get maximum profit in the future,
so don't panic when the price is high to buy, and don't panic to sell when our coin drops in price.
and have the courage to buy when the price is down.
There is no really right time to buy and sell because the market always moves randomly, especially in the short term, sometimes when we see the price movement of one of the coins that has increased, say for example the lowest price of a coin for 24 hours is in the area of $ 10 but then it happens increase to the price of $12 and stay in that area for a while, at that time maybe we will think that the $12 area will not be able to pass and think that the price will soon go down but in reality the market moves opposite from what we imagine and makes the coin price rising again past the $12 high area.
