In the early stage of the bull market, fear must be controlled, and in the later stage, greed must be controlled. No trade can be bought at the lowest or sold at the highest. As long as there is a reasonable profit, it is right. After 2-3 cycles, it will generally not be too bad, and those with good luck will be free after two cycles. After half a year, 60% of the coin prices are still at the foot of the mountain, most of which have increased by 5-10 times, and those with good luck also have 20-50 times, but the previous several cycles with hundredfold gains are more, but now they should be considered rare and hard to come by. In most cases, even if encountered, they cannot be held.
