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.
For traders this is not something new or that they haven't before, it's a known thing and don't know if you have seen there is a thread here where a good bot is being sold for a long time, that's the C.A.T and saying the truth it covers many popular exchanges including the poloniex too. Trading can be very dangerous especially for the newbie ones as there are lots of bots in poloniex especially and it's good to catch the 0.15% instead of 0.25% because there are lots of orders within 1 second.
