Honestly I don't see any new POW projects coming out. Its been like this for many years. This isn't 2015 again where everyday you would go to "Annoucements" section and get to instamine a new coin.

Most projects go to an ERC20 token, and those are only presold. Then if the project launches their own chain, its always POS. One reason for this is due to greed. Why give miners money? Also its due to environmental impacts and how much waste POW coins are creating.

Largest POW besides BTC is probably Litecoin or Dogecoin. 2nd place is probably Ethereum Classic. Hashrate peaked at 300 TH/s and now its below 200 TH/s. Maybe if enough miners give up, then it might be profitable again.
