Those projects who have a lot of investors and believe in themselves, usually, dont use bounty campaign for advertising.
Even strong projects need advertising to reach a larger audience and spread information about the project. Even the world's largest brands do this.
If you are a professional investor, you need to know that high priority or another words high rating projects collect hard cup without any problem.
I agree with you, for example, BitTorrent, which collected $7.2 million in 18 minutes. Or projects that collected hard cap in seconds Bread ($6 million) and Gifto ($3.4 million).
Yes, but these projects were a great marketing and news background. Now think , who knows about Invech that sketched white paper from binance? Do you think there is a chance that Invech collect at least a million dollars on IEO?
