OPNX exchange, which was recently tagged by Dubai’s VARA (Virtual Asset Regulatory Authority) as not regulated in the UAE, has been rumored to have investors from Bahrain, in the form of the Bahrain sovereign wealth fund given it has recently raised $25 million. According to a   tweet by BitMEXcrypto exchange founder Arthur Hayes, “A little birdie told me that OPNX has raised big money from Bahrain Sovereign Wealth Fund. They are trading via Tai Ping Shan. Be Warned. I want my fucking money.” Bahrain's sovereign fund Mumtalakt website didn't show any investment in OPNX directly but it is noted that the sovereign fund is an investor in Al Waha Fund whose portfolio consists of venture capital funds which could have invested in OPNX given that some of them have invested in crypto and blockchain entities before.  OPNX exchange  aims to tokenize users' claims to bankrupted crypto companies, allowing them to use bankruptcy claims as collateral to trade perpetuals'.
