You can sign up to test run a program Coinbase is doing where they pay you a small amount of ZRX to learn about 0x (aka Zero-ex).
I gave it a test run, and I have to say it was enjoyable and well worth the $3 in ZRX I got for doing it.
Further, I get the logic, because after that I feel that I can better explain 0x, and I feel more inclined to own ZRX in the future.
Sort of a win-win, and a really cool way to incentivize people to learn about other assets on Coinbase.
