Abu Dhabi is becoming a popular destination for crypto companies seeking eager investors and friendlier regulators, at a time when major markets like the US are experiencing an absence of both. Companies like Copper Technologies Ltd., Paxos Trust Co. and eToro Group Ltd. have turned to Abu Dhabi as a destination for global expansion in recent weeks, securing licenses or establishing parts of their crypto businesses inside the emirate’s international economic zone, known as the Abu Dhabi Global Market.
