I think you are right about the riskiness of Tron, substratum and verge being a gamble. That's why people are so excited about them. I think those investors who read posts and watch youtube see the potential but may not realize how far away they are from producing a final product. I'm not putting anything in I can't afford to lose as these tokens are a huge risk with a potential for growth. With 2018 shaping up to be a banner year for entry into the market more money will be coming in and these firms will be incentivised to come through with their promises.. at least we can hope
