Staking is good for environment, doesn't consuming electricity, producing heat, etc.
Running your computer does not consume electricity right?
All that "environmental" issues is a coverup to make the PoS thing look legit while it actually is not. They appeal to your emotions of saving the planet but you fail to realize that they are just putting up a fake mask to use that statement to make others buy their coins to start the staking. Of course when you have been staking coins, you need to sell them later on.
Where can you possible sell those coins if they are worthless on the reality?
To some bamboozled fools like bounty hunters telling them that staking is good for environment and PoW is bad likewise while actually they are looking to just exit the market. Thats how this endless cycle runs.
But i see many success PoW coins more than PoS coins, maybe it is because the miners community can make the coin more valuable.
That is a different thing. We should talk about Bitcoin which has been successful because it has some ideology behind it and rest are all copycat very few having anything good to develop on.
