Sure, you can get more PPC through PoS generation. But if nobody will accept them for transactions they're nothing more than toy money. The same thing has already happened to numerous alt-chains: IxCoin, I0Coin, CoiledCoin, SolidCoin, BBQCoin, etc.
I used to think that it would be smart to hold a small amount of the various alt-currencies in case one of them happened to get popular and take off some day in the future. Clearly that has not happened for any of them yet. Over time, I've come to realize that it never will. Why? Because once a new currency has been out for a few months, a small handful of miners can collect huge stockpiles of the new coins with relatively little effort. They're worth almost nothing, but alt-coin fans hold on to them just in case.
Let's use PPCoin as an example. Let's say that 2 years from now, Bitcoin's requirement for miners has proven to be a huge problem. The blockchain is too big for anyone to work with directly, and all mining is done by multi-million dollar quantum computers that only large institutions can afford. The banks collude to do most transactions off-chain so chargebacks are possible and anonymity is gone. The crypto community becomes disenfranchised and start looking for an alternative that the banks can't take over so easily.
Meanwhile, PPC enthusiasts have been happily improving the protocol, and it's now widely seen as the perfect solution to take crypto-currency "back to the people". The early adopters who still have their wallets with a few hundred thousand PPC are drooling in anticipation. All the waiting is about to pay off!
BUT IT WON'T. Community leaders won't start pushing PPC. All those bulging wallets will be seen as little more than a massive pre-mine. Instead, they'll grab the source, use it to create a new coin with a name that won't make all the kindergarteners giggle, change the crypto so the banks' quantum computers can't take it over, and launch it fresh.
In conclusion: if an alt-currency doesn't get merchant buy-in within the first few months of launch, it is destined to fail. Bitcoin is the only exception, and only because it was the first of its kind. Bitcoin's early adopters may very well become super wealthy some day, but alt-coins are not a path to riches. They're great for research, but terrible for investment.
my head says I agree with you entirely but my heart says shut up and I will be a millionaire when one of the altchains takes off, just a question of which one
also I would have to add that say there was an adoption of one of the alt coins by a large merchant... say ebay liked the idea of TRC over BTC as they saw an opportunity to make money from it by running their own SR equivalent on TOR then that would surely make the value of TRC worth it... however I do have to agree that it would make more sence for them to create their own coin and launch as Ecoins where they could have the initial advantage of mining at the start rather than joining months down the line once a huge number of coins are already in existance... and even if TRC did take off in such a way i'm sure we would see the bubbles and attempted busts of the currency.... especially if ebay were to take on a coin as i think there would be an outcry of users saying not to play into ebays hands etc...
also what happened to LTC being the silver of BTC's gold?? and that people will trade in LTC as BTC are just so precious and too valuable to trade on a day to day basis.. i know we are far from that at the moment, but do you think that LTC is in the same boat as a doomed to fail currency??
