Yes it is true. There is nothing wrong in investing in a small project and earn little by little. Being here in forum you can search for a big project where you can join and make you big profit. The least we can do is to search and have knowledge in every step we make so we will not gonna lose somethingg that we work hard.
in this case, I like your opinion. investing in a small project does not matter, because later on, it will also be a big advantage you get. so if the capital has accumulated, you can invest in a big project. but if you are prior to joining any project, first do some research first, so you will not be fooled by the project. so you need to be more careful in choosing the projects you will follow.
Good luck.
