I am pretty sure ecoin is being operated by XMLGOLD.eu
The strange thing is, in a way this site looks very similiar from the basic template to xmlgold and also the fact that xml implemented ecoin.eu codes right away after their launch make the things looking this way.
Officially, ecoin's company is incorporated and located here:
Wallet Capital Group Inc.
Panama City, 0819-10660, MB6063
El Dorado, Panama, Central America
With Financial License Number:
2543590-1-825330-2014-416047
and xmlgold
XML Corp. Suite 204 & 205, Victoria House, PO Box 1356, Victoria, Mahe, Seychelles, Reg No: 068955
Both are offshore companies, but that's not bad in any way. I know XMLGOLD operates since a long time without any larger issues.
Hope I could help you a bit.
