Bitcoin has fallen below the $80,000 mark, marking a significant decline from its April high of $126,200. The cryptocurrency's price has dropped to $80,600 in less than two months, nearly breaching the $80,000 level on Friday. This sharp downturn has resulted in substantial losses for long-position holders. Analyst Xiao Yihang is set to discuss the factors contributing to this decline and the potential for a market rebound in a live session on Tencent Meeting at 7 PM tonight.
