they are attracting more than enough investors already by focusing on nothing but new ways of scamming. and that is all they want, they want money and a lot of it in a very short time. and since most of those participating in this market also want the same things (fast profit) they don't care about utilities.
the end result of this trend is a lot of altcoins that have no use cases other than being pumped and dumped.

what the altcoins must focus on (that is if they want to survive in long term and have actual usages) is usability. they must start thinking about what they can bring to the table that is different than what we have already seen with bitcoin while taking care that what they change doesn't make them weaker and filled with bugs.
