I started selling. I was confused is it good to exit and buy low later.
Well, confusion is a trait of fud and fomo; and to be a successful trader you have to overcome and be able to handle your emotions. The best way to trade and earn is to sell the bulls and buy the bears; and if you are looking for an exact example to do so; there was a flash and quick dump today after bitcoin dropped. Did you take profits ?
Well if you are a trader, you have to know that at the moment there is a correction that you can take advantage of, it is good, sometimes you have to follow the line of least resistance, but you must understand that this means that when the correction ends the price can rise from bitcoin and you can continue buying, it is not too late, the market will always give you opportunities to enter.
