I have a project which is about cooperation and regulation marketplace.
What is the idea of your project? I see it's strange to have a project "about cooperation and regulation marketplace". It is like a seminar or discussion, not a project.
All backend frontend developments are done. Whitepaper is ready! All mathematical and code backround is ready!
So why keep it secret? Publish your idea and what your project is, at least without coding.
but i have not enough fund for advertesiments and hiring so i sell the project for pay my educational costs.
If your project is unique, advertising costs are not great. For example, you can create a bounty campaign on this forum and pay for your own tokens will cost you nothing.
If we want to evaluate the price based on the interface design of the site, the price is $5.
Also, you say price is 1 BTC & in the site price is 20 BTC this is ($19000 discount)
