Beware of Poloniex,
They use bots to pump and dump coins and ponzi schemes, at the moment the exchange is pumping DASH which is a ponzi scheme, they create these big pumps, attract investors who short them, them keep them stuck for weeks. If you dont know Poloniex is designed to suck in investors, use bots to create fake volume.
Doubt it, because bots wouldn't help much at this point anyways. They're already so big in the exchange world.
