A few weeks ago I noticed Coinbase was giving away ZRX at invite-only Coinbase Earn, so I got on the wait list and a couple days later I received an email invite. All I had to do was watch 3 short videos and answer 3 questions and I received 9.375 ZRX, which was worth $3.00, in my Coinbase wallet. I didn't think much about what to do with it until yesterday when I decided to see if I could turn it into more by trading it on Coinbase Pro. This should be fun.
