Far too many in my opinion, but I do agree that at least the top 50 to 75 aren't scams or doomed to failure.  Everything below that is questionable.

Op, you are absolutely correct about these ico projects trying to impose blockchain tech onto areas where it isn't suitable, and I've seen some crazy ideas since I've been watching.  It's ridiculous to me that these projects keep trying to do what amounts to the same thing over and over...and they keep getting investors! 

The coins I mentioned on coinmarketcap might survive, but tokens are another story.  I would venture that the overwhelming majority are going to be worth zero, and it won't even take years for this to happen like it will with some of the worst altcoins.  It might take no more than months after launching for most of these crap tokens.  It's a fitting fate, too.
