Staking is an old idea. Those who got in early of course made a lot of profits during the bull run but if you look long term at POS coins,,, you almost see that mainly their value slowly erodes over time, because of course people will sell their interest from staked coins, just until they gain back their investment. Many will continue to stake until they have 2x or 3x compounded coins, before selling again. Seems like a good idea at first until you see everything drop.

There is no trick and no secret. Everything stops working after a while.
