The two Indian siblings have started their own cryptocurrency company and earn $30,000 each month by mining crypto. Fourteen-year-old Ishaan Thakur and his sister, 9-year-old Aanya are mining Bitcoin, Ethereum, and Ravencoin. With the help of their father, Manish Raj, the siblings have set up Flifer Technologies in April. They started the business with a single computer in a room desk and now they have a rented-out data center in Dallas, Texas.
