I’m not sure the mining will benefit the user but I could be 100% wrong.
@rabbitdidar53 Thanks for the suggestion, you will be contacted by the Admins directly if they are interested 
It sure isn’t friendly to the user.
I mean while the mining mode hour is active I’m unsure if the site owner profits (probably unlikely) most probably 000webhost will reap the little benefits to further improve the 100% free service.
Yeah that’s correct. It’s well explained in what @daugis said. The good thing is their sites won’t be sleeping.
