There's absolutely no use for altcoins except to provide some different way to do things that Bitcoin may or not adopt. 90% are scams too, 100% are easily manipulated so the market itself is a joke. You can make money of course if you have some inside tips.

As for the future, don't fool yourself with nice talk and features, you can make money trading but there's more chance you hit the lottery than to ride one of these projects "to the moon".
