I'm Lithuanian myself. I remember long time ago i was searching for Spectrocoin office. This one:
UAB Spectro Finance
Vilniaus g. 31
Vilnius LT-01402
Lithuania
And guess what? It does not exists, i'm i asked some people in that building, but they never heard about spectrocoin.
And the telephone +44 20 3769 5474 is fake too.
In one source I found another address of their office - Auros al. 68, iauliai. Don't know is it fake or real, but office located in iauliai instead of Vilnius or Kaunas looks odd for me.
