This is a good strategy in investing because you are giving yourself a small assurance that it won't get loss but remember also that your success in your investment will depend on your research on the project. Team that is developing the project is important too they must dedicated and continue to develop the project.
Making research before invest is the key to make profits. Developers team is the key to successfull project and i think beside that, marketing strategy is important to spread the word about project. If project known by many people, there is a chance more investor coming and creating demand will increase the price
I agree with all of you that whatever is involved in a project affects the success and failure of a project, if the one involved in the project is an active team, I am also sure that the project will be successful and the coin will have a price so that the profits will be obtained participants who joined.
Since there are so many scam project these days, all that was mentioned above is agreeable, we can't just blindly choosing project to invest on, and one of the reason tho choose an active project would be to avoid from getting trapped in a fake or unsuccessful project.
