marketing will not help if there is no product. therefore, in any case, I would like technical details.
It sounds right. But in the world of cryptocurrencies, most of these projects do not have products but are already traded on the exchange. This is not correct, but this does not mean that if your project does not have a product, then marketing is not needed.
It sounds right too. Marketing is often ahead of the product, but the product, technical details, roadmap must evolve. Otherwise, a distrust of the campaign arises.
