so far in the market I feel like Coinbase has acted as one of the only – and certainly most vocal – trustworthy marketplaces. Especially with a concept like cryptocurrency which in and of itself seems a bit "sketchy" to most (especially becuase of its association with black markets), many competing marketplaces dont instill a lot of confidence in users. That may be something as simple as UX/UI or branding, either of which would solidly add Robinhood into the "easy to understand for non-techies" category along with Coinbase.
