btc-e, bitfinex, poloniex??
if you are new to trading then you'd better stay away from "arbitrage trading" and try to start with "regular trading" instead.
poloniex is fully altcoin trading and it has no fiat market apart from USDT which is another altcoin with the price of USD. try trading on bittrex or poloniex as start and as I said do normal trades of buying low and selling high.
the arbitrage trading that is the topic here is somewhat advanced and a very hard thing to pull off successfully because of many different factors such as fees, timing and the difference.
p.s. try making a new topic next time instead of bumping a topic from 2015!
