Okay, what if there was PoW or PoS what would change? Likewise, it is not profitable for miners and coin holders when the coin is not traded or has a very low price tag!
There is a big difference between PoW and PoS mining. In PoS mining it is necessary to hold tokens of the project for stake. In PoW mining you do not have to hold tokens you can sell your tokens or coins when you wont.
