We can gauge the sell-off severity using the Short-Term Holder Cost-Basis and its -1 standard deviation band:

* Short-Term Holder Cost-Basis: $64,300

* Short-Term Holder Cost-Basis -1SD: $49,600

The Spot price nearly reached the -1SD band, with only 7.1% of trading days (364 out of 5139) recording a lower deviation. This highlights the rapid pace of the market decline.
