With time, the Diwali investment portfolio has expanded, from gold and diamond to stocks and real estate, and now cryptocurrencies. The virtual currency has been successful in capturing the otherwise conservative Indian market so much so, that as per recent reports, even top Bollywood stars like Amitabh Bachchan have jumped on the bandwagon. As per the latest reports, the 79-year-old megastar has been roped in as the brand ambassador for CoinDCX, while another TV commercial by CoinSwitch is already live with superstar Ranveer Singh promoting crypto trading.
