2-5 cents per 24 hours seems fairly equivalent to ads, actually.
Ad CPM (or more appropriately, RPM) seems to average somewhere around $2.50 (that's per thousand impressions). If these thousand users were on the site for 24 hours, that would be $20-$50, a more realistic scenario would be users on a site for a few minutes, generating comparable revenue to ad impressions.
On my desktop (which, not coincidentally, is where you'd have the best results trying to mine cryptocurrencies), I would honestly prefer this over tracking cookies, obnoxious and intrusive ads, extra network connections, and all that crap. And I run an ad-blocker, so this will let you get some revenue while ad RPM will be 0. On my phone or laptop using battery power, you're not going to have any success mining and I'm not going to want this. (I also run an ad blocker on those, so...yeah).
Also, if the payment was higher than fractions of a cent, people would start "freezing" the site the moment it loaded - just as, back in the day, we disconnected our phone line modems as soon as the page we needed finished downloading, to avoid paying the phone company for time not spent transferring data.
