I bet it's a witch^W exchange's craft, ask/bid appears then immediate sell/buy happens, this is how you pump volume to attract customers. Hitbtc is/have been famous for this kind of advertisement.
ah. yeah. A while back it just jumped up to that one day and has been like that since. And someone had told me they were making a little money daytrading BIP, so I assumed that's what it was.
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.
I think you are wrong. Cryptopia not playing that ever. I am in Cryptopia for two years or more and I have never seen manipulation. . . You do not contemplate the possibility of "C.A.T traderbot" and some people with 20-30 btc to play and take out dividends in an easy way, because I see large volume and expensive, but fast and cheap purchases, with a lot of profit with few moves. You also do not contemplate the possibility that internal exchange currency 'DOT' has given great benefits to investors and these reinvest in ALT's business. I repeat, Cryptopia is the most friendly, fresh and honest exchange you can find, with a big difference.
If you have doubts because I come from puppy-socks, I'll tell you that I'm probably the bad ass of Cryptopia.
You have a good day

I do know that two people have told me they were making money day trading BipCoin.
