Four years ago, $BTC experienced a drop from 19k to 16k, about 15-17% of its asset value at that time, turning altcoins into a bloodbath. That day coincided with Thanksgiving, earning it the affectionate name 'Thanksgiving Massacre'. After four years, during the recent halving event in April, we witnessed a repeat of the scenario from four years ago when $BTC fell from 73k to ~55k. This drop proved that altcoins rely on the breath of BTC. After two weeks of hell, newcomers felt like they had gone through months of suffering, with both long and short positions resulting in losses, whether in spot or futures trading. Now, $BTC is reaching a new peak, accompanied by much regret for missing the boat, but you don't need to worry too much because BTC is adjusting and the chart has not yet stabilized. All statistical numbers are merely meaningless figures in the face of manipulation from the giants. The scenario of BTC falling four years ago still exists as a reminder that 'greed will lead to loss.'
