There's really no upside to continuing POW. Only downsides, lower prices, and malicious or unintended forks.
Upsides to continuing PoW, just for the sake of argument-
1. Continued free publicity via WTM/Crypto-coinZ/Crypt0-zone
2. More opportunity for small buyers to get in with less risk
3. Far easier to build a userbase and community via mining than staking.
1. Free publicity to bring more miners. Not investors, not buyers. Miners/Sellers don't invest their $$$ in a way that helps the coin. Their money goes to hardware vendors and electric companies. Then they sell/dump on the exchanges. We don't need this kind of publicity. Compare this to MN owners and Stakers, they are incentivized to first BUY, and take coins off the market and hold them. They help the community and other investors by stabilizing the price. The miners just mine and dump.
2. Far far more risk in buying mining hardware and setting up, than simply buying the coin and staking/MN.
3. See #1. What kind of "community" are you looking to build? The "community" that only takes? That switches from coin to coin with lightening speed chasing profits, and then dumping those coins on the market and often straight into the bids? That's not community. Those are not loyal holders and buyers.
Sure there are a very very small number of miners that do end up buying and holding bwk and are great to have in the community. No doubt about it. But they are a small minority in the greater sea of miners. Most don't care one bit about the coins they profit from, or the long term future and health of the network. For example: If they can all pile into one pool to make more money, they do it, regardless of the consequences for the network.
