That chart is log-scale. The index fell by more than half between December and February, but you wouldn't know it by glancing at the chart.

Good eye, that is sketchy. The entire industry seems to be floating on FOMO right now though, so it definitely serves that purpose.

It should be labeled or otherwise shown, but I think that semi-log is the most appropriate choice of scale for long-term price change graphs like this. I can buy linear-linear for intraday charts, but anything long-term should be log-linear IMO.
