Advantage of using peercoin

Hi everyone!

I’m new to cryptocurrency and I wanted to validate some of the advantages I’ve read about this one. It has a low maintenance cost and is a safe and fast investment to make transactions. I know that it is best to be aware of the market and I found good statistics on this site: What do you think? And what do the editors refer to when they say “It has Proof of Stake Algorithm and Proof of work system which ensures smoother mining”?

What exactly do you mean by this?

They mean that peercoin is a POW/POS hybrid which makes it more resilient to attacks
