So theres this site: https://www.spacemining.io/?ref=171786 (hope you don't mind the referral link) that give you 100 GH/s FREE for signing up. The site is a HYIP (high yield investment programme) and has been going for around 10/11 days now. It is $15 for 1.5 TH of mining power! Very cheap. Like I said, HYIP, therefore, the site will most likely scam very soon.
However this company has not asked any YouTubers to promote this site yet as this is what usually happens with these. I believe it will be around for at least another 10 days so you can make your investment back or just enjoy the FREE 100 GH! Enjoy!
