If you are a project's investor, you should do your own research, deep investigation to understand what the team they have, what the product is, what is their capacity. No one but you can estimate the real value of the project. Anyway, that's the only way to make right investments and avoid waisting of time on unworthy ideas.
and also don't forget, before investing in a project you must also be able to manage your financial management properly by not investing all your money in ICO projects. my advice to minimize losses is better to invest real with BTC, ICO project problems I don't want to say much, because most of them are scams. stay careful with that
