I understand that noise.cash has made some updates to the point that what they call FreeTips (FTs) are going to disappear soon. They are now distributing contributions in a different way that has to do with likes (♥ in this case). The more interaction between users and the more likes, the more Tips ♥ each user earns. A tip ♥ is equivalent to $0,001.
