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?
I hhave never heard about this exchange before. How many of their tokens are you holding, again how are you sure the volume on their platform is real, most Chinese exchanges have this issue of fake volume just looking for how Coinmarketcap.com is going to resolve this issue
