I think, this Project was just there for his fun in his leisure time. Maybe he's busy again.
Or there's another possibility that it was for him to scam us. Although we didn't pay for the tokens, but some people were trading URHOC on etherdelta. Maybe... DE was selling some of his tokens. Just stating a possibility.
However, I have little hope till yourchain website is working.
I told the same think many months ago. This was really a nice fraud strategy. Many people bought on etherdelta, the people that didn't receive the airdrop. The only think that is strange for me is that behind the github account of yourchain there is SharedMoca, try to search who is on linkedin. The person that has this account appear trust and real, so i don't understand what happen.
