Does Signature campaign increase ICO credibility? I see few good ICOs recently using Signature campaign to promote their private sale.
Some ICOs still rely heavily on mere words, a makeshift design to raise funding as before has completely failed. The birth of Ido/ILo is reflecting quite well the liquidity problem, a beta product or testnet must be ready. Jax network is one such project. Signature campaigns are just a form of marketing, promoting visuals and clicks. It is not a criterion to consider the level of trust for a project.
