Because of the roadmap, I've been following this coin since the the mining period. The only people who could dump to 6500 and still make money would be those who were in on the instamine. Anyone in on the instamine would be a dev. It's clear that these devs are good enough that they could simply make little releases and dump their bags on real support. They wouldn't have to be that good for a plan like that to work.
If that wasn't the devs, the dumpers lost money because that's an all time low for this coin on any exchange, even with dpos which could have bumped their holdings by maybe 25% at most. I don't think the devs would be dumb enough to dump themselves out of 10-20 BTC like that, but devs can be pretty dumb about trading, even when they hold the cards. They might have seen the lack of buy support after their paper wallet release and panicked to get out. We'll see if they come back and make more releases. One thing is certain: they will need to produce real tech to get this coin noticed. Paper wallets won't cut it. My guess is that they are not paper wallet devs, but I could be wrong.
