A little strange, why does Vitalik promote other coins instead?
He doesn't. He's open minded enough to have other projects 'rent' his knowledge and connections.
So curious about his statement, even though Eth has a better chance to continue to rise and be under bitcoin.
Many Eth communities want Eth to remain strong and become an altcoin that is a more innovative and popular platform.
Vitalik has trashed his own coin numerous times already, and he'll keep doing that because he understand where it lacks, and he isn't shy of speaking out how hard it sucks in certain fields.

Institutional adoption™ and Partnerships™, that alone says enough.
He has spoken out against everything that's centralized last year, and XRP is just a muscular version of a privately owned database.
