Nigeria has escalated its scrutiny of cryptocurrency operations within its borders, demanding transaction histories from Binance for its top 100 local users and detaining two senior Binance executives, Nadeem Anjarwalla and Tigran Gambaryan, for three weeks. The Nigerian government is attempting to impose a $10 billion fine on Binance, amidst proposals for stricter regulations on foreign crypto exchanges. These proposed regulations include requiring foreign crypto exchanges to incorporate locally, establish a local office, and face a fivefold increase in registration fees for cryptocurrency exchange licenses. Additionally, the Nigerian Securities and Exchange Commission (SEC) has proposed a 400% increase in supervision fees for crypto firms, as part of efforts to address recent currency woes. The detained executives include an American and a British citizen, with no word from either government about their detained citizens or actions being taken.
