Would love to get an update from OP.
I doubt we will see an update, in his post he said:
that would not require much time investment per week.
I didn't notice he wish to invest money! And if you don't invest time and skills or money, you can't generate any income! Basically those two are first choices, you will work for it (with your time, energy, knowledge) or you can buy some shares (staking coins, dividends from some exchange, or casino). There's no third option, it's either this or that in my opinion! I have couple investments from which I have some passive income (daily, weekly or monthly, depends on investment), but it's nothing much, couple dollars here and there, I didn't wish to invest huge amounts in them, so I don't expect much, I am satisfied with couple dollars here and there.
