I agree, this is really awesome. I think it will only be a matter of time before Coinbase starts to add more altcoins as well. They will have a hard time staying competitive if they do not especially since they charge fees. I am curious though as to what Robinhood's revenue stream is if they are not charging fees. That usually worries me when I do not see a clear profit path for a company like this. But, they have been trading regular stocks for quite some time now so they are obviously doing something right.
