If you get tokens on ICO, that means the ICO project has already worked ? Or you can still get tokens from failed projects ?
There's still a chance that the project will fail through time even after ICO. One of the reason is that the lack of support coming from the community or the team behind the project sucks that the project can't progress. So in choosing an ICO to support be sure to check for that factors, anyway I suggest to research about menlo.one its an ICO that currently I'm supporting.
