Crypto exchange Luno launched BTC Savings Wallet that promises its users a targeted rate of 4% interest per annum. There are no fixed terms and no admin fees, the company said. "Almost 95% of our customers have said they want to earn interest on their bitcoin," the company said, adding that the new product "arrives at a time when traditional investments have shown vulnerability at a time of crisis." The company claims it has more than five million global customers spanning over 40 countries.
