$BTC As long as you pay attention to BTC, you will know whether the other altcoins are rising or falling. Look carefully at the five-minute trend chart. If Bitcoin is falling in a straight line in five minutes, the altcoin you are paying attention to has not fallen sharply, so find the low point. Buy. The first thing every day is to look at the daily chart of the previous day, and then set the alarm clock for today's lowest point at the 1/3 position. If the last half hour of the previous day was a state of recovery, then this may be the entry point for the first half of today. Sell at a certain point. In the second half, there will be a correction and decline, and then set an alarm to the previous 1/3 position of the day. Be sure to learn to read wiring diagrams.
