How easily can you change a coin from PoW to PoS? I would be fully into Quark if this ever happened. If we could do that, not only would we have a secure network, but we would attract many new investors who don't want to miss out on staking rewards.
ROI for big projects is necessary, and supported on a few other websites. The Scharmbeck Foundation (and eventually scandal) was funded like a stock would be and raised 5 million dollars. It promised high dividends. We shouldn't directly associate Quark coin with a project, and we must make sure that the developers are trustworthy.
I'm trying to figure out what a profitable project would be that could help a coin (possibly Quark, but whatever would maximize my potential) as we speak. I think developing android and ios games that use cryptos for 'upgrade purchases' or 'in-game stores' might be one project I undertake. Although a game that rewards you with coins, like a faucet would definitely popularize a coin (at the expense of whoever donates the coins).
I don't know how easily you could add POS - it may be impossible for all I know. That and the wallet updates are great ideas, but I don't know about the implementation, which is why I deferred those to Max.
I think android games might work, but ios games seem out given apple's current stance.
I agree that whatever project was funded would need strong and reputable devs.
