Because they need money to make vacation for weeks, while other devs work 24/7 to succeed their project 
I just noticed even blockfolio is showing the old vsync coin, i checked on the website and its STILL under construction, the last time i have checked the status was 2 month ago?!?! wtf, how long does it take to make a website?? this is just a weekend project, not a serious coin, so of course it will dump every time you see some green candles. good luck! 

So ppl get banned from the group for asking simple questions like "how is the development going?" smells like scam to me,
since the mofo dev was working for weeks on the new website, and it looks like a blue colored crap. no development. no progress. ppl get banned for asking questions. fk this scam. im out.

I would suggest PROXY and Logarithm.

When Airdrop 3 & 4?
Or is this Project already over?

Another LiteCoin Copycat?
