Well Veltor was a scam, the original dev (John Connor) ditched out, and the remaining devs tried to salvage it but were wholly unprepared. It's just a classic scam and clusterfuck.
Could be. Still, my point stands. Take another coin, Verge for example. Apart from smaller submissions, it is a one man show. Now, what would happen if the dev stopped working on it, for whatever reason?
In case of Veltor, if it was a scam or not, users could choose not to go the ICO route or dump their coins, but to take over the project and continue working on it. But it is unlikely this is going to happen.
