BTW, Bitbay from my experience is a great place when you can earn on arbitrage, because of permanent overpricing comparing to market :) For instance now:
-ETH on Bitbay (http://bit.ly/2wASwfK) is listed at $354 when on Bitfinex (http://bit.ly/2jeOM8V) at 327.7$ and accordingly;
-BTC on Bitbay: $4850, on Bitfinex: $4500
-Lisk on Bitbay: $7.5 on average market: $6.32
