I have seen many ICOs' having advisors for namesake and only a few have for real. Can we believe a project based on the Advisors?
Or is it necessary for ICOs' to have Advisors before Token sale? Seen some using Bounty campaign to get Advisors.
As far as I know, ICO is hiring their financial advisers and market adviser to be able to communicate and understand the market, to be able to be safe when market is unfavorable, and to be able to attract more people that will going to support their project. And that doesn't necessarily means they are compulsory. Hire as you can because you are the one who needs to pay them.
