As long as you properly credit the source and provide a link (and it sounds like you’re already on top of this!) no objection at all! In fact, even better, if you put it on a public platform, I’ll tweet it out for you!
Oh, and by the way, if you get my book “How to explain bitcoin to your mum” as a gift (sadly only available in English) each one comes with £10 free in bitcoin(or the euro equivalent of £10 if in Europe) courtesy of my sponsors, Luno. Great way to get people to understand it and actually get them started in the bitcoin space.
All the best!
