I think at the start of 2018 XRP had about 46 direct FIAT on ramps globally.  Currently there are about 210+ FIAT pairings for XRP globally.  No other digital asset is building global liquidity like XRP, especially throughout Asia, Middle East, Brazil, Philippines and Canada.  In Jan 2018 Coinbase definitely had the upper hand but at this point I'd say that coinbase NEEDED XRP more though its no doubt mutually beneficial.  Especially when you consider that Bakkt, Etoro and others will be breaking into the US market likely later this summer/fall.   I expect further delays into the Fall regarding these exchanges but they are coming.  Coinbase will be a very small fish 2 years from now.
