Investment in both would be a good option but if I would choose one over the other then investment in education would be prioritize over the other. I believe some people in here invest in bitcoin through joining in campaigns so that they can finance their education which I think is a good option. It would depend on what country are you from though on how will you choose between the two.
In first world countries, they may choose to invest in bitcoin instead of education especially when going to a college/university because it is expensive while in developing countries, the school fees is not that expensive compared to developed countries but still there are people having a hard time going to school that's why one of the key to finance it is through investment in bitcoin.
