I discovered Coinhive 3 days ago on HN, and decided to give it a try on one of my smaller websites, as an experiment.

For those who don’t know what Coinhive is, this is their intro on their website :

Coinhive offers a JavaScript miner for the Monero Blockchain (Why Monero?) that you can embed in your website. Your users run the miner directly in their Browser and mine XMR for you in turn for an ad-free experience, in-game currency or whatever incentives you can come up with.

Basically your visitors/users mine crypto-currencies (Monero here) with their CPU for you in exchange for the content you are providing, it’s a possible alternatives to ads, and a better monetization option in my opinion

I tried it on a website with approx 1k visits a day, with a 0:55 seconds session duration average last month. The objective was to replace the non-intrusive ads I’m currently displaying.

Here are the stats I gathered :

Coinhive dashboard
Coinhive average hash

It seems that I’m am constantly between 150–450 Hashes/s, which is pretty low. It seems logical: the website having at any minute between 5 and 15 visitors, that’s an average of 20–25 Hashes/s per user

So I made 0.00947 XMR in 60 hours, a whopping $0.89, that’s $0.36 a day

For this exact website, it’s 4 to 5 times less than what it makes with non-intrusive ads (banner + text only)

As stated on Coinhive, the embedded JS miner is well suited for websites with longer sessions duration average. This website isn’t probably a good use case for Coinhive’s embedded JS miner, but from the small sample data I have, it’s not a viable alternative to ads

Hope this helps if you were curious about remplacing ads with Coinhive’s Embeddable JavaScript Crypto Miner !

Feel free to reach out on Twitter if you have comments or questions.

Note: The mined Monero (XMR) can be sold at Binance

Edit: One downside is that Coinhive is pretty expensive (they take a 30% fee), so I’ve switched to CryptoLoot recently, with a 12% fee, and I’m happy with it for now
