The volume of Catex.io is real, is this exchange based in China giving you a voucher? The exchange was born only a year ago, they have a CATT token (2 billion) which currently costs very little $ 0.000482 ..... could it be an interesting investment?
Investing in a token because it is cheap is not a good idea. A shit project won't make any impact at the longtime. Apart from being an exchange, I wouldn't look at it for another chance but because it is an exchange, maybe it could get it right in the future time.
