Top 1 and top 2 deserve their spots.
I rarely see projects like Gladius, they're almost like the Golem project but with a way different take. More focused on DDoS protection and specializing in content delivery networks.
And with IndaHash, it's already an existing successful project and their just trying to integrate blockchain technology.
Do we need a special protection Project only for ddos protection? I don't think so.
People started to conduct very specific projects and this is no good. You don't need millions to create a ddos enemy system or protection. There is already companies doing this when you pay them.
