For me there are a lots of overvalued coins, but I think that the most overvalued coins are: Cardano, Tron, EOS and Bitcoin Gold

good selection

these are over priced for sure

ANY coin with narrow distribution is over priced because you can never know fair market value for it.

From myself I can add IOTa. A lot of hype and the only thing that works - the wallet. 146% overpriced, but idea is not bad!
