DNotes They put a lot of efforts to market this! And They claims that Bitcoin Alternative DNotes Launches World’s First Digital Currency Employee Incentive Benefits Plan.

I liked DNotes too, but more than a year ago my investor forced me to sell 100s of thousands @ about 190 satoshi. In my opinion, DNotes is in top 5-10 cryptocurrencies if we talk about steady and natural growth. No hype, no pumps & dumps and it was even 10% premined.

I like DNotes as well. Its price is stable and now stand at over 6000 satoshi.

I say me   16-18 hours a day, 7 days a week, for 2 years and still going  

I jest, but Nxt do have a lot of devs all of which are very active, so I would go with them for a product that is released.  Though I expect the Ether guys wont be far behind in terms of raw developer man hours when it finally launches.

hands down as of today 2015-June... its got to be NXT. I tried many other altcoin wallets and seriously. nothing compares to what the nxt devs got so far...

Below are some screenshots of the "local" native client. Many people that haven't installed the application thinks the following screenshots is a centralized website, but its not. It's the actual live app on your computer, not a website. I was shocked when i first made this realization too.

Ethereum is also a "supposedly" promising one too. Thats assuming they release something already. You must give them credit for the hype and marketing they're capable of... But until a production release happens, its vaporware to me.
