My personal frustration that has seriously made me wonder if ai want to be involved in alt coins anymore is the case of Qora. A complete new code that has shown itself to be superior to NXT technically on many levels is completely overlooked because it's marketing is completely lacking. I personally am not technical so you have to go research to know in detail why, I want to put more substance but I'm working secondhand from others I respect. Anyway, I've come to the conclusion that marketing is all that matters and anticipation and convincing of some future time a coin is valuable.
Newsflash, Bitcoin is the only coin that is going to be accepted in the mainstream we are just developing the system that people will use to hold a bitcoin and other assets. Can you imagine as the mainstream gets familiar with Bitcoin then they are told about even the quality coins like Darkcoin and Litecoin, people will just say this is all a joke we can't put our money in this. But people don't care about reality they want to believe in yet another dumb coin with dumb promises.
All I want is a wallet that in a user friendly way can hold my assets, ie Bitcoin, Fiat, precious metals and maybe a few other exotic assets. A bunch of second gen coins can do this now, we don't need any more, it's like having a hundred Facebooks to choose from.
I think the real issue with Alts is that people view features as the new way to get rich like the early bitcoiners did. The problem is that the rise creates wealth seekers and if/when the coin isn't successful they all lose their money. Or people just interested in using it for it's features lose money. It's more like creating a penny stock with a prospectus that is probably overtly misleading (the ones that are short term successful usually are anyway) in order to sell it to shareholders.
Then the dumpers move on to something that's next. The altcoin scene is much more like stocks trying to sell you on bitcoins future when absolutely no coin has bitcoins future. Bitcoin already solved the problem and jumping to a new currency renders an old currency worthless. And the entire system isn't sustainable. The champions for alt coins are more people who are refining their art of jumping out of pennystockcoins at the peak of the hype. They thrive and survive off of the insanity that renders all alts useless for long term adoption.
That said I do believe there is room for one anon coin and a smart blockchain. Now that bitcoin is mainstream and the gov is paying attention to the blockchain. Many of bitcoins original uses will continue to be threatened.
I also believe that smart coin & anon coin winner will push litecoin out over the next year. There won't be enough room for it. I'm not sure who the anon & smart blockchain winner will be yet ...
