I totally agree that Steem would make a fantastic addition to Coinbase. I read their Medium article about their new coin listing process, which is currently free but may incur a fee in the future. Here is the link to the article: https://blog.coinbase.com/new-asset-listing-process-a83ef296a0f3 . The form required to list is a Google Forms application and has to be submitted by a "founder or developer", a "major investor (over $1M)" or an "executive or employee". Now would be the time to make that application.
