I think I have to skip the 3rd and 7th guide for newbies. Bitcoin mining and all related to ICO should be the next step after newbies learn the basic knowledge of bitcoin or crypto in general. Once we have to teach newbies, we should not jump into complicated thing like ICO or Mining hardware unless the newbie's main purpose is for that thing but still, the basic knowledge should be learned first.
Honestly, even the old ones including me aren't that familiar in bitcoin mining technicalities and just those basic stuff so I think it isn't that necessary if you are not into mining.
Though this is bitcoin stuff but this should be in beginners and help section yet somehow newbies don't lurk in that section.
