I just found out about coinIMP and tested it for a day or 2.
You can use this on your blog or faucet or wathever your website is about.
Every visitor will mine with some hashes for you.
you can choose between the 2 crypto's: Webchain or Monero.
This can be an extra income and cryptogathering.
Seems pretty interesting if you ask me. Before there was coinhive and some others.
Another one you can use that works like this is JSEcoin.
They both have a wordpress-plugin.
Defenitly worth taking a look at it.
