Very selective. Before it was not so and I did not put much thought into the coin I am investing in before I put my money because I knew that I could trust majprity of the projects but now there are so many scams that the reverse is the case and I know that I cannot trust majority of the projects, so careful checks.
In any case, the choice of the project is the number one difficulty. even if you personally analyze all the information and check the complete documentation of a project, its still not up to 100% and guarantees its authenticity or success.
