Those traders who are selling low and buying high are literally lack of experience and are panic sellers in reality. They don't know that it's essential just to wait during the dips and it's not a requirement to sell just for them to recover some losses. They can even recover by just holding for longer term.
Of course buying in high prices and selling them when its low is a very obvious loss.
It's a mistake that's happening during these times.
Yeah It is the common mistake most of people use to do at the time of fall in price, if they will hold bitcoin at low price it will be good for them. it is good to use the opportunity and buy bitcoin at very low price at the time of dump, then hold it with patience, dont panic your bitcoin till it become triple than the amount you have invested in bitcoin, then after that sell it, again buy more bitcoin with the help of earned money from bitcoin so this way you will walk on the successful path.
