Coinbase is more than just an exchange it is more of an endorsement of originality. If for any reason you get to scale through coinbase listing, you are on tour way to the top as a great project to be looked at BG investors.
Instead of getting listed on Coinbase which is almost impossible for small/new projects, I was thinking of using Shopify as an alternative to sell coins. Basically everyone that want's to sell brownie coin would have to setup a shopify store and start selling through shopify.
Let me know what you think
