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?
Absolutly not! dont invest in coin which only has low liquidity. it doesnt good for you investment even if you do long term
Pair
CATT/BTC just has 0.113 btc volume in this day, it very low
there are many coins better than it, choose wisely
