I don't know if you have found a phenomenon, that is, the high point of the altcoin rebound is lower than one time, BTC fluctuates at a high level of 100,000 ~ 110,000, and the cottage continues to break new lows, and now the trend of the cottage is to fall by 90% and then rebound at the bottom by 100%, giving people the illusion of doubling, making people feel that the cottage season is coming, and as a result, open the monthly line and see, there are still 108,000 miles away from the historical high, and when you chase it falls by 50%, BTC falls by 1%, and the cottage falls by 20%, When the BTC high shock finishes a new high, you will find that the copycat is not as high as BTC at 60,000, if BTC fluctuates at the high level for another half a year, 90% of the copycats in this market are afraid to go to zero, of course, there are individual cottages that can hit new highs, but it is too difficult for ordinary retail investors to catch and choose, so it is better to buy BTC directly, anyway, BTC will only fall harder if the copycat falls.
