Don't invest in ICOs without working products.

I agree with your statement, but also investing into a project just because it has a working project will only end in tears as well.

The most important thing is to do research into everything, if they have a working product that's a bonus, but it shouldn't take away from the fact that you still need to have a great team behind it, solid concept and all the numbers need to be in the right place.

True that.

Even a codebase / github is not good enough if it is not working.  Anyone who knows what they are doing can throw together a bunch of nice looking code.  The hard part is getting it to work.
