It's important to distinguish here.  Are you trying to make a list of coins that are likely to be a poor investment, or coins that are shady or misleading (and may be scams)?  A lot of poor investments may be legitimate and a lot of shady coins may end up having a high price.

One example of a shady coin is IOTA - while it contains a lot of buzzwords about IoT, it is not actually usable on IoT devices and is also insecure as it could be targeted quite easily by 34% attacks.
