While that may be one of the best videos yet about bitcoin mining, I'd have appreciated a NSFW tag/warning. I've edited your subject accordingly.
i dont see what about it is NSFW? if its on youtube it can be played in a work place.
This is not a true statement. There is no nudity if it is on youtube that does not mean it is safe for work. Try putting up a Calandar of women in Bikinis in an office setting.. You'd get in trouble and have to talk it down before 1/4 of the day was over.
