Coinigy is just a trading platform.. You send your BTC to the exchange you like.. Example: Poloniex or Bittrex .. then you can trade on that exchange using the Poloniex website, or you can set up a personal A.P.I. and enter that into Coinigy, and from then on Coinigy and Poloniex are linked.. So think of Coinigy as your remote control for your account at Poloniex (or which ever exchange you choose)
