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.
No, increasing number of shitcoins does not mean a direct corelation exists between the rise in the number of exchanges. If anything the number of shit-exchanges should reduce down and there should be an unofficial official group that would either approve an exchange or disprove it. More number of shit exchanges are definitely a loss.
