One of the main things you want to evaluate when looking at any ICO is the technology.
This technology should be something that provides real value to or solve a problem related to the marketplace. 
I think TravelerToken meets this criteria. The goal of the company is to create a shared technical and economic infrastructure. This infrastructure will represent a simplified standard that not only minimizes costs for customers but also maximizes profits for providers. Moreover, the infrastructure will not be limited to the travel sector but open for all.
And this is just the tip of the iceberg!
