Email from Betterment one hour ago:

"Important update regarding unauthorized message

Earlier this evening you may have received a message referencing a crypto-related Betterment promotion.

This was an unauthorized message sent via a third-party system we use for marketing and other customer communications. Please note that this is not a real offer and should be disregarded. We apologize for any confusion."

I just got this Betterment app notification

Why would anyone use betterment anyway? What do they actually offer that's even remotely attractive?
