As more tokens keep coming into the market, it is assumed that more cyptocurrency exchanges will raise. this, we all know have a risk effect which is that hackers are empowered to try their luck especially on vulnerable ones. The good side is that more tokens has the oportunity of getting listed on exchanges.
example; NCHT( nano healthcare) project just got listed on etherbase exchange.
The more competition that better of us consumers. The downside is that hackers will keep thriving on this new or even old exchanges. So it's really very very tough if you would assume to put up a exchange right now. Not just the initially money you have to shoulder, but the amount of responsibility just to keep it going and away from the hands of hackers.
