The simple fact of seeing so much publicity about it everywhere (especially in faucets) and the great efforts to obtain referrals made by this type of user, shows that it is nothing more than another multilevel scheme, or perhaps a ponzi. Not even the possibility of "mining" from the cell phone seems so convincing to use this as the main argument to promote this project, so I do not think it is worth even making an attempt to participate in it, compromising the security of our mobile device just for pennies.
