I know signature campagns exists on this forum for very log time . I was wondering , do they really help to promote ICO , i know they spend a lot of money to pay bitcointalk members to wear their singatures and make posts . Do they really make profit out of this ?
If people are going to invest on such project, developers are scattering these advertise everywhere on the internet so it does really help them to gather more people that's interested in their projects. You will see to their websites the different platform that they were using to make contact to almost everyone not just in here but also on the other.
And also if you are the developer you really should have a financial support to continue your project, it is not just a small projects that wants to get some attention so they can easily gain some investors. It is a paid project to secure the success of their campaign.
