People need to know themselves. I have discovered that I can find some good targets and buy them, but I will gradually lose my chips in the subsequent various operations, and even turn from profit to loss. I remember a big guy said that in the currency circle, you must know how to buy and sell, and even selling accounts for a large part.
Only then did I truly understand this sentence. If you can buy, it can only mean that you are lucky and you have entered the door of the currency circle, but you can sell to be a qualified trader. $BTC
