bigger market share, more revenue ... there is nothing else there :) My guess is that if there was enough clients for bitcoin, they would not support eth 

Fair.

What made you decide to support ETH instead of remaining pure Bitcoin?

No KYC at Casa, so that's a big distinction between us and Unchained & Swan.

Biggest differences between Casa and Nunchuk & Keeper is that we A) support other assets and B) have higher levels of consultation that expand beyond just the key management / asset security.
