I have seen many PoS coins decline in value over time, making your stakes less profitable than ever.
However, even though this happens, there are a very few coins that prove to become worth to hold for the long term.
Nevertheless, I would like to know which PoS would be best to invest into these days, according to market movement. I'm always on the look for good PoS coins to put my money into, and make my profits grow for the long term.

Neblio is a very profitable pos coin, especially since the project is great and the developer always deliver their promise. They are ahead of the roadmap, already listed in binance and have a solid community. The APR is only 10% and it's hard to earn stake reward if you only have less than 1000 coin but if you can buy more than 1000 then you will be satisfied with the pos reward. You get the reward and the coin price increase with further development of the project. Don't buy pos that has big APR because the value will go down for sure.
