Good question at the end brether! Can't wait to see what Coinbase adds next. What do you think they will have by the end of the year?
I'm guessing:
Dash
Monero
Steem
Golem (if brass release is successful)
Augur (if they have a working version by the end of the year)
Doge (because doge)
Nem
Ripple (I hope not, but I could see it happening)
