In a first, NEM coin, a branch of NXT, is trying to give away equal shares of coins to prevent hoarders.
https://bitcointalk.org/index.php?topic=440185However, as long as crypto currencies can be mined and dumped on the marketplace with enough hype, I suspect it will always be done. However I believe alt currencies are reaching a critical mass where they might end up destroying themselves. The number of clones in just the past week is starting to accelerate. Weeding through the ones with a good team behind them like NEM/NXT takes work.
Hopefully some of these great features that these coins promise like the direct currency trading, data storage, etc. start to actually be used and implemented.
