I think I might be suffering from PTCD aka Post Traumatic Crash Disorder... Seeing those numbers fly and red lightsabers swing took me back to January/February dip... Did we have a doctor on the forum? ?
Coinbase would add some measure of liquidity to the XRP ecosystem. The question is how much of a boost would one exchange be?
I honestly don't think people are too obstructed now. As annoying as it is to pay transfer fees, those that purchase XRP have done their homework, and don't suffer from the usual short attention span that we've seen with the investors in the early years of crypto. If they need to transfer their BTC to a separate exchange and then purchase XRP, most will do it.
That being said, easier is always better - I definitely support a listing on Coinbase (and RobinHood).
