If coinbase will accept XRP,they did it a long time ago which didnt happen,so it means that will remain the same.Coinbase doesnt want to have a centralzied shitcoin in their exchange that is why XRP wont have a chance,it is for the greater good because if this coin dominats the market cryptocurrencies will eventually become centralized just like what XRP is.
This is true,if coinbase will really accept this coin they have done it a long time ago which didnt happen.They could accept XRP when there is strong rumour last year that caused a lot of people to get FOMO,that turned into bloodbath from the investors of XRP,because the FUD has been around for while that cause a lot of people being fooled.
