Does anyone use hcaptcha for their websites?

So I wanted to know whether hcaptcha might be a good way of content locking for compensation, but there's no clear estimate for earnings per 1000 captchas. How much money you get depends on your visitors' accuracy, that much is understandable.
Apparently, the earnings are measured in HMT which is equivalent to 1$, but also you earn points, not HMT?? Do you have any experience with hcaptcha payouts?

my interested mind wants to know is it worthy?

I have never thought of this, gonna use this on few of my sites and report back.
