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?
considering some of the comments above, I think we need to be more careful to invest in this project, besides that there is no data displayed on the CMC regarding CATT tokens. and there is no trading volume (CATT pair) in their exchanges
