"space for nerds" ? Cryptocurrency is for everyone. Cryptocurrency does not differ your level of tech science, education, income and etc. You dont have to know coding languages, have MBA in finance trading and have a decade of stock trading experience to be in. You could just download an app to your mobile, add card and be a part of crypto world.
