Regrets or no regrets, the truth is that there's no investment that doesn't have any risk. That's also the reason why it's not so good to only have one income source.
Actually, every investment has its own risk that is attached to it, whether high risk or small risk. It is always a risk, and we will be the ones to manage it while investing in such an investment. However, you also said the truth by having multiple sources of income so that if plan A doesn’t work out, plan B will.
