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.
More crypto exchanges is really good thing too to get traders but not many after trading exchanges that enough liquidity for the trading to be done so you need to be careful on where your doing trading are you will get stuck for too long and also don't forget to read their fee structure.
