Fot me the most important thing in exchanges is the reputation, I saw a lot of exchanges being hacked, so now I only stick with the high reputation exchanges like bittrex and binance, good customer support also an important point, low transaction fees and a lot of good coin to trade
Well it's always the good price that catch my attention towards this system. Who would have not want a good price, right? That's all we want here and just like everyone I want to experience that as much as possible. Well it gets my interest whenever the valueprice is so high because I knkw that the opportunity to earn is better.
