I'd still give credits to the devs for being upfront and honest about their failure.
Any suggestion on what to mine next? I have no luck with roto due to its insane difficulty level and i was a few hours late to jump in.

that's it folks, straight from the horse's mouth, failure of their algos and withdrawal of support.
Please proceed calmly and orderly to the exit, don't forget to turn the light off if you are the last person.

yes, please pump it back to 0.002 so that my sell order will go through, i promise i won't dump again as i would run out of AIR by then  

Sound BS to me, free market and self sustaining vs manipulation to keep 5% weekly increase trend and price doubling every 3 months, what did you just say again?

The collaboration is basically you give them your BTC for their premined AIR.
Looks like they have run out of BTC to prop up the price or they have cashed out and leave people like you in the cold. Amazing how the faceless men can make money from thin air, done and dusted.
