Ask HN: What's the product Coinbase is selling?

Please, answer only if you are using or used the product in the past.

I was genuinely curious but could it use it given their territory based / regulation limitations. As I moved last year to the Emirates I applied and activated the account, and could not understand what am I buying.

It seems as if the main feed in the app is not about buying or selling BTC or ETH.

In simple terms, what is the problem they are solving?
