I read your article and I can see the same effects, but in general I cannot agree on the analysis of cause.
The price of basically every crypto asset droped during last weeks. It proves nothing. Still, the timeframe is to short to pull such big claims. Please, take it as a friendly critics.
And HE tokens? I'm engaged in these and the drop of price is not change of the trend either. And POB specifically might be dropping from lack of leadership not HBD APR growing.
We would see a bunch of different metrics going crazy in such case.
