I think this is a fake but these are all likely candidates for the upcoming additions to Coinbase's offerings. We know from their FAQ that BCH is coming to the platform and we'll be able to withdraw it from our accounts on Jan 1, 2018. I can't foresee a reason why Coinbase would allow users to withdraw BCH but would not include it in the list of coins coming to the platform in this screenshot.
RE: Coinbase adding $DASH, $XRP & $XMR to their platform!
