bad coins/scam likely altcoins.
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.
