It doesn't seem like you've tried diversifying your income resources through investing in cryptocurrencies (Bitcoin in particular), because your proposals appeal to the traditional, classic market and don't take into account the current changes in the era of globalization and advanced technologies. Today, there are businessmen investing huge budgets in projects that are bound to be risky, yet they take risks. For example, Elon Musk raised huge sums of money from angel investors in his craziest projects, including manned missions to the moon and Mars, in addition to his failed self-driving car project, from which he generated no returns and was halted before it even began. Diversifying income streams varies according to each person's capabilities, his tolerance for risk, and the extent to which he is willing to take risks.
