Good projects should provide you with this information to begin with. If they do not they you must ask yourself why you are investing in them and probably dump your coins, unless you can make more later on through other peoples silliness and future investments that bring the price up more but that is a risk.
Apart from fraudulent projects, then all the same, useless projects appear on the market, because quite a lot of new ideas appear not only every year, but almost every month and there is competition over the ways to invest in a particular project. The whole problem is that the developers are not working hard on their project, but, first of all, they aim to earn as much money as possible, attracting more investors. The situation today has already changed and differs from 2016, and the most important thing to understand is that only an interesting and sought-after project can attract more investment funds, and if this idea and especially the final product will be appreciated in society, then the high price of a coin on cryptocurrency exchanges provided.
People are fooled with ease they need to be more careful. Most projects are nothing more than an idea. Ideas do change the world but I am sorry to say that a dead idea that never sees the light of day changes nothing. It doesn't matter if you have the best idea ever. If others do not see it and see it beginning to work then nothing will become of it. Most projects you see the idea but there are flaws in the idea and it is not true passion it is just a quick way to extort people of their money with an idea that you do believe in but know if it goes wrong you can just quit.
