I joined CoinEx to purchased some CET when it first came out and have been pretty happy, not only with the nice gains from the token but also from CoinEx's CET dividends. 80% of trading profits is distributed to CET holders. 20% goes to miners, and they own the majority of the miners, but who cares. There aren't even many stocks these days that pay dividends let alone tokens. They came up with a clever win-win-win strategy (us - the exchange - and the miners).
CoinEx randomly does airdrops. I now nothing about the CARD token except that I'm getting a whole bunch of free ones. CoinEx will take a snapshot of you CET token balance on 2:00 July 9th, 2018 (UTC). You have to have at least 10,000 CET tokens (they're only in the $0.12 to $0.13 range right now).
Here's the link to the airdrop article:
