$BTC Now the mechanism of currency rise and fall has indeed changed. At present, the big cake has not seen a sharp drop. It has risen from the bottom for several months and the current maximum correction is only about 20 points. It has reached the top twice and bottomed out twice in one and a half months. I feel that the most cost-effective investment method is still spot fixed investment, and low positions and low leverage are still recommended for contracts. I personally analyze trends from the perspective of human nature and interests. I basically don’t look at any thin technical curves, and I don’t understand them. In a word, spot can be held; contracts, money is not so easy to make, and if you make money, it’s just the right bet.
