Total rubbish for the most part. The main and obvious choice would certainly be that it is already listen on or definitely going to be listed on an exchange. What good are tokens/coins if you cannot even sell them?
I see a lot of under the radar projects with very few participants because people look for all the flashy ANN's even though half of them are actually scams and will never ever be sold anywhere and basically are just decorations for your wallet.
If a coin is able to be sold already than you can't go wrong.
