As of right now, Coinbase does not sell VGX. However, they have been known to add new assets in the past, so there is a possibility that they may add VGX in the future.
NOTE: Warning Note: Coinbase does not currently offer the ability to buy, sell, or trade VGX. This may change in the future, so please check back periodically for updates. Investors should carefully review all associated risks before investing in any cryptocurrency.
If they do add VGX, it is likely that they will only allow users to buy and sell it, and not store it on the platform.
