Every project has its own break, however we cant broadcast significant year for these projects growth it always depends on development and adoption. Even if the project is 100% feasible but no adopters then definitely it will be a big problem, the key is always on the team.
You're right but OP did clarify his reason. For me, I dont judge a project based on what they lack cause it's normal for every new projects to have a flaws. Tachyon advantage is they already on the market but it is not necessary means that when it comes to new idea they are dominant compare to the two other projects. Adoption is always the priority and massive users, if the two has many users even they dont have market yet then what is the meaning of that? It's also a matter of innovation not just market price value.
