Considering the statement of Bill gates saying cryptocurrency is bad, I realized that people are just concerned about the negative aspect of how cryptocurrencies can be used forgetting that these kinda activities and actions of people already existed before Satoshi even thought of building the blockchain technology and Bitcoin. The world needs to focus of the positive aspects of cryptocurrencies and their platforms which are the solutions to gaps seen in the world we find ourselves in.
Very good point there. 2017 really marked a bad year for crypto/blockchain as a whole and it's kinda hard to trust again tbh.
True! I know a lot of friends that got scammed and the team founders just went off. How can this projects nowadays get the people's trust back?
I would say that IEO is the best way to go now. IEO is everything ICO should have been back then. Safer, more reliable, better controlled. How crazy the trend has been, ICO, to STO, to IEO. What's next?

In terms of your question with getting the communities trust back, it should be an effort coming from the founding team IMO. One sign that I look at in terms of legitimacy is how active they are in engaging, if they are attending crypto events, etc. I stumbled across a project in where you can invest in great ideas which is
Tecra. They even won an award recently at the World blockchain summit at Taipei for the best startup pitch. I think those are the factors you need to look at. I would laugh at Bill gates if the news I read about Microsoft launching their own cryptocurrency become true. (Unless this is one of his strategies?)
