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 do not recommend investing in these coins, I have catex coins that cannot even be sold because the price of the fee is not comparable. the increase in catex coins is also unpredictable and may not be able to expect more. so I thought maybe you could change to other types of coins for investment
