Well, it's not an entirely wrong speculation, Bitcoin decreased 90% back in 2013-2015, from that all time high of 1200 ish., so if you want to take a history record of how volatile Bitcoin can be, this would be the worst case scenario by far.

But it's highly unlikely, i suspect BTC to settle near 5-8k Levels, it woulden't suprise me at all if Bitcoin fell back to 5k.
