All the trades are fake you can notice it by looking at action, order book is untouched, all deals simply appears out of thin air you barely will notice orders matching marking history. it's selfish trading by exchange with 0 fees indeed or just a scam by pumpers trying to show fake volume and probably pump it.
Stop talking like a weirdo!!! prove this stupid shit before you start sounding like CNN ya fake news fk lol!
All you have to do is watch it to see the fake volume. There are legit trades, but very few. If it's not Cryptopia doing it, someone is throwing away a lot of money in fees.
