Ok, the site was originally oominer.com and it has several mining “sub-sites”, whatever they are called. I only happen to start my mining activity under GPU Mining, and found that 0.05BTC will take me a long while to reach!
All you need is your BTC wallet address, paste it on the field and start mining. Don’t have a computer, so my phone is doing all the work for me now.
Not sure when or why the domain name was changed to kene.host, but you can check out the link below:
