Again, go read the laws concerning these matters before continuing to argue on a baseless foundation. Evan Duffield has been the main, sole developer of Dash no matter how long or how brief. Vertoe has stated that Dash is centralized. A cryptocurrency needs to meet two criteria to be defined as decentralized, Dash only met/meets one.
c. De-Centralized Virtual Currencies
A final type of convertible virtual currency activity involves a de-centralized convertible virtual currency (1) that has no central repository and no single administrator, and (2) that persons may obtain by their own computing or manufacturing effort.
Oh, Vertoe said it, case closed in that case. Disgruntled ex-team members never lie or misrepresent, so we know this must be true. Evan may be the main developer, but to say he is the sole developer is an outright lie. Troll harder.
If you could read troll, notice how there's "no matter how long or how brief". Vertoie saying that Dash is centralized is a huge hit in case you don't understand. He admitted that Evan was the sole force behind Dash down to the how the code is orchestrated. I'm sure it's up for debate whether he's been the 'sole' developer of Dash if the 'work' of other "developers" can be seen as neglible(kind of like sockpuppets).
