Here I will say the first thing, that it is very difficult to gain the trust of a new coin like other Biggest Trusttable coins, in short, it is not possible to do it. But you can look at the background of other coins why they have reached this stage today or gained so much trust for investors to invest. I think a new coin should have a minset first to gain trust, they will keep their project innovating, keeping favours of users in mind. And constantly keeping up with and updating technology.  Match your words and actions.  Sometimes a good marketing strategy or promotion is very important to gain trust.
