Hold cash in your hand. The bull will come but it will be short-lived. If you look at the months, there are charts that mimic the ups and downs in 2021. There will be a bull market in certain coins for a short period of time around the end of August or the beginning of September. It is not a condition that BTC must be bullish at 70-80k. When it drops to 30,000 or 50,000, movement may begin in altcoins. The important thing is the dominance movement. Be sure to have backup cash and don't act on excitement and FOMO.
