I prefer to choose for investment those coins that have a lower cost, but with a great potential for price growth. Usually I find such coins after the ICO, watch how much the project has raised funds during the ICO, how the team implements the plans recorded in White Paper, how the project develops and follows the community's actions, because the pledge of the prospective project is a professional and responsible team , as well as the active community of the project.
I agree with you, because I also choose coins for purchase during the Pre-ICO, if I'm confident in the team and the project, but if I have doubts, then I'm waiting to enter the exchange and then I buy. Now I have found inexpensive coins with great growth potential: IPSX, HBZ, XYO. They all have grandiose plans and teams of professionals.
