In an exchange of cryptocurrencies (say an exchange of ETH to BTC on poloniex or kraken), do you still pay a fee to the miners to verify the transaction(s) or is it included in the exchange fees?
That exchange takes place entirely on the exchange's books. Miners don't verify those transactions. Someone will pay transaction fees when you deposit or withdraw to and from the exchange.
