dev online yesterday but not say anything...
He was online on may 30, not yesterday.
Guys I think you need to face up to the unfortunate realisation that the dev has done a runner and won't be back.
I could see this happening weeks ago and sold my 50K of CYP at around 1000 sat (which involved me losing about a third of what I'd put in having bought at 1500). The fact the website was offline for so long (and hasn't ever come back on-line) and the CypherCoin2015 Twitter account hasn't tweeted since 25/Apr, plus that appallingly lame video which was pretty much the last thing the dev did, said to me "uh oh....this one's a 'last out turn off the lights' situation". And it looks like that's the case.
I'm very sorry for anyone that has hung on thinking this will come good but it's clear it's not going to. The dev started putting a few things in his (or her) posts just prior to my decision to bale that were clear indicators. He'd not been on-line for a week or so and mentioned "problems with job/living issue etc"; almost a guarantee there's an exit in the wind.
One would like to think this is salvageable but I don't think it is given what was being worked on and promised.
Shame on you Cypher7A69, after taking people's BTC through the IEO process you have promised commitment to this project and now left people high and dry with yet another worthless crypto. You have committed a crime which you will be punished for once found out.
