I'm not sure - it depends on the platform. I think ICO mania has caused some people to over invest so I see the value likely getting a lot lower before it rises again now that we are a few days in. Long term do I think it could have the same market cap as Ether? Sure. That would put it at $25 - $35 per token.
But, that's only if the EOS platform is launched and the blockchain is formed successfully.
