poloniex was good a long time ago. Now it's just a crap exchange.
Use binance and bittrex.
Okex and several others are adding decred in the US market, what is the reason poloniex draw decred?
Just a ridiculous attempt at market manipulation or even ignorance.
They rated decred as a security token.
decred isn't a token, it is a coin. And we also didn't have ICO.
