Binance founder and CEO Changpeng Zhao (CZ) published his advice to crypto companies on Twitter: "1. Maintain a 1:1 reserve and the problem will go away. 2. Don't lend money to customers to make money, let venture capitalists do it. 3. To generate income, charge transparent fees for your services, such as facilitating transactions. 5. If transaction costs are too high, use blockchain technology to reduce costs." Finally, CZ concluded that the principle of the above advice is to "keep your business simple."
