Coinhive review: Embeddable JavaScript Crypto Miner - 3 days in

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.
