1. No business address
Trusting a business that has limited published business information can be risky, liability is easily averted.
1. Heavily paid marketing campaign
Attracting too much attention can easily overvalue a project, this may cause a huge spike after an exchange listing, only to drop immediately after.
Gladius is a prime example of a company attempting to capitalize off the merging of two technologies, p2p nodes powered by tokens, and industry standard DDoS protection techniques. Users become nodes and earn tokens to filter and analyze traffic, a great incentive for users, but for clients requiring protection, this approach is sub par compared to the trusted, centralized services offered by giants such as Cloudflare and Verisign.
Gladius claims to have been invested in heavily by Krypton Capital, the company has previously claimed to have invested in the ICO copy cat Viuly. Such business dealings lead us to believe an unscrupulous bonus deal may have been made in exchange for publicity. The standard ICO model has been corrupted by a private pre-sale and public pre-sale, even with the vesting periods, ICO investors will likely see a huge drop in token value after the token hits the exchange as none of these promises can be enforced.
