In the huge BTC trading market, we need to know that how much money we can make depends on our mentality, and our mentality in turn will act on the money we make. When we set the take profit, we can close the position at the profit that we have imagined each time we invest, cultivate the confidence of investment, and develop good habits. If we don't just make a profit, we always have the mentality of "waiting for the market to rise a few more points", but the gains outweigh the losses. Profits will add up, and rich people can't be made in a day. Therefore, maintaining a good mindset is really a clever BTC trading technique.
