I don't think there's anything wrong with POS coins, but I don't think they have much life outside of use for avid traders (this is all just my uninformed opinion). I think there's an inherent perception issue with a POS coin for newcomers, especially noobs to cryptos... to make the process to get involved having to learn how/where to safely get BTC (which is a big enough trust hurdle), then have to figure out you need to go to yet another exchange to get the coin you want (which to be honest, most of these to an outside could come across as pretty sketchy), then have to explain how POS actually works... these are all too much to expect people to grasp.

When I first got into BTC, I was like "SHIT! IMMA GONNA MAKE SOME MONEY"... got some basics from Google, got some USB miners for BTC and was on my way to riches! Until I actually started to grasp the economy and realized those USBs were pretty much worthless... but you know what? I did get a minute amount of BTC from them, learned more about mining and progressed from there.

I'm struggling with wording, it's all about perception, but I think it's easier to understand and get behind a coin that is still "mineable" (whether profitable or not), vs. a coin that primarily lives for traders on exchanges.... maybe some of this makes sense.
