Coins that give you extra bonus for not trading your coins? Wow what a horrible idea! Don't you realize what robust trading does? REDUCES volatility in the price! The more coins being traded the more constant the price is! The only legitimate reason to offer huge staking bonuses is so that you can pump and dump as the coin owner and no one can sell in order to stop your dump from making their holdings worthless!
Coin with the most robust trading: Bitcoin. Not staking, just mined, and heavily traded. Miners put it out all the time, it is traded with the most volume. Can you say that Bitcoin is any less volatile than POS coins? I've actually seen so many POS with pretty stable values.
And no, I am not a pos lover nor do I stake any longer. I used to, and am even thinking of doing it again, but not just yet. Staking as a means of securing the network was a brilliant idea, maybe a lot of pitfalls but far from horrible.
You clearly misunderstood staking if you think there's only one legit reason to offer "bonuses". Please google Proof of Stake.
