I think that for a successful ICO you need money and a lot of money, on the other hand, it is strange for me when some unimportant project is trying to collect 20 - 30 million dollars.
Of course money is needed, but even more important is what this money will be spent on. Projects with clear goals and a plan for spending are always ahead of everyone else. So it's funny when my friends ask me for an opinion about the project without white paper or without a product. I prefer not to waste time on such projects. It is better to invest in those projects that have been on the market for a long time, this is a guaranteed profit in the future. I treat all new projects with a certain amount of skepticism.
