Bitcoins or such crypto-currencies are not legal tender and those indulging in such transactions are doing it at their own risk, Finance Minister Arun Jaitley said yesterday as MPs expressed concern over trading on these platforms.During the Question Hour in Rajya Sabha, DMK member Kanimozhi sought to know whether the government was considering regulating crypto-currencies like Bitcoin and Ethereum, as India "accounts for more than 11 per cent" of such trade globally.
