As of now, there is no clear answer as to whether or not UFO is on Coinbase. However, there are several theories as to why this may be the case. One theory is that Coinbase is holding off on listing UFO until the project has made more progress. This makes sense from a business standpoint, as listing a new asset on an exchange can be a risky and costly endeavor. By waiting to list UFO until the project has made more progress, Coinbase can minimize its risk and avoid any potential losses. Another theory is that Coinbase is waiting for UFO to get listed on another major exchange before listing it themselves.
This would give UFO more exposure and liquidity, making it a more attractive asset for Coinbase to list. However, this theory is somewhat unlikely, as listing UFO on another exchange would likely not have a significant impact on its price or liquidity. Overall, the reason for why UFO is not currently listed on Coinbase remains unknown. However, it is likely that either Coinbase is waiting for the project to make more progress or that they are waiting for UFO to get listed on another major exchange.
