As of right now, eRSDL is not on Coinbase. However, this could change in the future as the company has been known to list new assets from time to time.
NOTE: This is a scam! Coinbase does not support eRSDL, and any claims that it does are false. Do not give out your personal or financial information to anyone claiming to be associated with Coinbase or eRSDL. Be aware of any offers that seem too good to be true, as they likely are. If you have any questions or concerns, please contact Coinbase directly for help.
For now, investors will have to look elsewhere to purchase this digital currency.
