BTC is also a reminder to everyone that it will rebound to around 84k this week. If 84k cannot support it, wait for 82k. It has broken through the level for 4 hours and has no rebound force. Except for some strong cryptocurrencies that are under control, other altcoins have been following the market and falling. It's not the right time to go long yet. I suggest waiting for at least one large volume drop to rebound.
