Waves must be one of old coin which had roots into this forum:
https://coinmarketcap.com/currencies/wavesIf my memory serves me better, I guess they did signature campaign as well.
If we are able to find any pattern on surviving projects from their early days, we may get chances to figure out a similar one from current/future new projects.
Sounds like a good idea. Still, I like to suggest you do not believe into altcoins because some may fail even after 2 years or even after 5 years also. But, I am really surprised we had ICO projects for almost every sector like solar, agri, platforms for doctors, education, drones, file hosting etc etc but I could not recall any one them launched their real time business.
