What about the whitepaper and roadmap ? You are in touch whit dev and don't even report what he said about this ? Or did he just threw those miners at your mail without further explanations ?
What he means in a sugar coated way is that the dev is gone and since he is not the dev himself he is looking for devs from the community to help him. Until then it is status quo. Best case scenario is that a dev/devs step up in the next month or so before the next high block reward to sort out POS issues as well as make the algorithm more resistant to GPU miners.
It has now turned into a long term project and with no imminent improvements on the cards, it would be best to sit back and stake and focus attention elsewhere for a few months.
