Someone was running a bot program (I think) for that UNITY coin
Every time I tried to sell my coins, the same person would under bid me, a half second later
The way I could tell something was going on, is when I looked at the "Sell Orders List"
I would see the same person selling the exact same number of coins, but the price kept changing every half second
It was as if the same person was pressing the sell button, then cancelling the order, then pressing the sell button again, but a lower price, then cancelling again, over & over
The price was changing literally every half second
And the shit was going on for hours
It had to be some kind of bot program
Fam, I had to send an email trouble ticket to Poloniex tech support, to complain
Coincidentally..... a couple hours after I sent the email to Poloniex.....the bot program stopped

And there was such a low trading volume for that coin, I couldn't find anyone to buy it from me
Shit was like trying to sell ice to an Eskimo
Here was the email trouble ticket I sent:
"Hi, I'm a recent member of Poloniex. I bought some UNITY, a couple days ago. I have an issue because I can't sell it. There seems to be an automated bot, or something, that always underbids me whenever I try to sell my coins. And he keeps manipulating the sell price.
When you go to the UNITY coin, and look at the "sell orders" list, there's someone who is trying to sell exactly 6.56469940 units. But his sell price keeps changing every second to try & underbid other sellers.
Is this even allowed on Poloniex, because it seems like its cheating, to artificially keep the price low, so others can buy really cheap!"
