So let me say they have a lot of room for improvement! With as much business as they have they should be cutting down on the basic coinbase fees
Their value is in how Very Simple it is to set up and User Interface. I will say when your average 40-60 year old who has minimum computer experience decided to invest with crypto, It will either be with a broker or Coinbase. Very simple to use and understand for our technically challenged baby boomers. I agree with @abomadje that someone and it will be sooner than later, will come and in a 3 move checkmate takeout CB Revealing their hand when the additional crypto coins besides the original 5, in the proceess they were added was at the least a desperate attempt to "keep up" at best. They are huge and have branding established but all it will take is a couple of shiny new features and the right timing marketing on the next run, can make CB a memory of the past..
