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?
If you use some kind of common white paper from other projects as a sample, I see nothing wrong with that. This cannot be considered plagiarism.
As for marketing in IEO projects, investors, in any case, should learn about such projects from somewhere. The only exception may be cases when large investors appear as a result of private negotiations.
