Quite rightly there are already a lot of cryptocurrencies in the market, and most of them either just copy the features of other coins or they promise features that they really cannot offer. I don't think we need anymore new coins, they more often than not turn out to be useless coins without any actual utility or even scam coins at the worst. Having said that, if people need a coin with an actual utility, they'd have to use Bitcoin or a few other altcoins that have utility, as for speculation, they can pick the coins they think would pump and give them ROI, but no more new coins with fake promises!
