One problem can't solve from first, if new investor can't trust new fresh coin why they don't invest in old coin. We several good coin already exists in cryptocurrency even with very low price. Even I don't think there could be a trust problem. All solution is now is the correction time!!
Well, we cannot blame them for having that kind of thinking to attain such kind of decision making because all of us do have our different and own experiences with regard to engaging into different projects. There are people who are already afraid of getting into such project because of the fear that the same failure or scam might happen once again because money is a real deal in any investment engagement we do participate. The problem is not just the trust that makes the prices of the new Altcoins get lower but also its competitiveness because if it is really a good project no matter what other people say, well for my perception, that coin will still be interesting for the sight of the potential investors because it is attractive as it is. Well, maintaining the credibility of a project is really in need to regain people's trust and to change the generalized concept that all projects are the same because they are truly not.
