I'm confused. Were you looking for a cryptocoin that was promising 1,500% gains?
Anyone promising a safe 15% return in a world where your savings account earns 0.15% interest is trying to rob you.
Stablegains had nothing going for it, in fact it had all of the risk with none of the reward. 1500% APYs are usually attached to LPs carrying huge risks of impermanent loss rather than stablecoin staking and are usually very transient in that they evaporate within hours.
FWIW I disagree with Anchor being termed a ponzi.
