I think there is nothing you can do, maybe you can only hope and miracles come
Accept and move forward, there's nothing else left but to accept the fact that if the project fall and developers decided to runaway then there's nothing left but miracles.
This is a risk from the world of cryptocurrency, this is the digital world and even the track records of blockchains developers can be faked
More likely if you invest with unknown coins who don't have any clear path. If developers are just aiming for money and fakes out every information about them and their works.
If you want to get profit from cryptocurrency then you must be prepared for the risks, such as delisted coins / tokens from exchangers
It's a must to do your in-depth research before investing your money, the chance of succeeding is always in your hands, it will depends from how you really engaged with your yourself in regards to the project that you'll going to invest your money.
