Stacks is a premined scam that implements a forever ICO model - bitcoin holders send bitcoin to stacks holders to receive stacks tokens.

Stack promoters use affinity marketing and misleading terminology to hide this fact. Naive retail users are their target.

Due to the premine, founders and investors receive the majority of the bitcoin sent into the forever ICO which they then use to advertise the scam to more naive retail users. Incredibly predatory.
