POS doesn't require any special equipment, also there is no a running cost, i.e. it is just a regular electricity consumption of your laptop. Let's say, POS is accessible for everybody easier than POW. That's why i prefer this way. Also there are pools for those unable to keep a wallet open 24/7. In this way POS looks like a truly passive income: you need just get coins, place them to pool and await for an income. Of course, a risk of scam remains, but where is not this risk? Also POW or any other doesn't protect from such risks.
well some pos coins don't require any special hardware and some do[for higher earning] , the downside to pos is that your coins are exposed. i think all those pos coins should implement cold staking like aura.
