That's a good reason behind your post, but imagine that there are diplomats, lawyers, musicians, artists and even taxi drivers using this forums. I am in the 2nd category, but I know people corresponding the rest of the professions I listed above. 

I think the background does not matter much for cryptocurrencies, because it is a new field and everyone can learn and start trading. For your further reference, I can also add, that I know people from banks and government interested in cryptocurrencies (but they don't speak about that much), professors, singers, even hairdressers. However, I was quite surprised when I my friend's GF asked about cryptos, as she is currently a pole dancer (with a lower IQ). 

P.S. I am not arguing that pole dancers have lower IQ, it's just about her.
