Technically it's an ICO from EU, the Czech Republic.
But the most of the team members are Russian, indeed.

Worldcore had been attacked by the black PR-campaign from Questra and it's suffering badly on the falling market but it's definitely not scam. They've payd promised bounties. They have never used any pump and dump schemes, they participate a lot in various EU fintech conferences, launched some their own features. Btw, the big update is coming on the 1st of September. What I can reprimand their management for is slow reaction to the external challenges. But it's not about scam at all.
