If anything, I would think, I'd like to see how your app or Surfer will be able to also take a direct BTC or ETH in to wallet. Which would allow me to spend fast this coins here too or hold. I don't see any app here doing it in steemit in this way.
I be very happy when I go in Esteem wallet and I can hold there BTC and ETH also ... what I can fast use to Boost or promo my posts. Or use this two coins fast to get SP more what can also Boost all steem up in long run.

I hope it is ok what I say, I can think lot. :) @good-karma
