When the crash of No. 5 happened, I reminded everyone not to sell at a loss. When Bitcoin reached $100,000, many retail investors said they would wait for $30,000 to buy, leading to panic selling. Now everyone is experiencing FOMO. I remind everyone again that $80,000 for Bitcoin is a hurdle. Keep a close watch on Bitcoin, and do not let it break 5,000 points; altcoins will be halved.
