Well, Coinbase is a success and it have Coin in it's name.
If the service/product is good enough, the name doesn't matter.
It's like BMW, Dell, Apple. Those names if not pathetic, have no mean, and those are ridicously big names around the world.
That is what it means to create a Trade Mark™. Apple or Dell are just random word - yet they are recognized all around the world and 99% of people in civilized countries know about that companies.
In bitcoin we need something similar, crypto companies with not necessary Bitcoin related names.
