tap to earn project don't come with any certainty that you will get certain range of pay out by the end of the project. most of the information you get about how the calculation of points works and how it will affect how you will end up being paid are speculation that are used to keep the project active till it completion. i would never recommend tapping a project a whole two years, that is too long to even start with. airdrops are better done when you are not expecting to much from the result of the project or else you get to face disappointment by the end of the project.

instead of investing that number of years in a project that is probably new in the market, using that effort to gather an already existing coin that is already doing well will even yield better profit than this.
