Many project are now starting off with a mvp/demo, it probably means than in the icos field the bar will raise and people, hopefully, will become wiser and stop investing in project which are promising unrealistic goals.
Yes, that's true. You should expect a at least a demo for most projects. I'm glad EHF will have their MVP ready before the ICO.
It should be that way. We need to know in what are we investing. The whitepaper is OK but a demo is always better.
