For steady income anything with bitcoin is not possible i think. I suggest you find lower risk investment, such as 510% interested, and live off the interest. If you invest like $100k then it is $5,000-$10,000/ year. Bitcoin is risky. I dont think that bitcoin can provide you with steady income. It's always fluctuating.
100k dollars is not a small sum. Not so many young people have such savings. Earn 5K-10K dollars a year is not very much and not enough to a year for them to live. I think this amount is enough to protect your savings from inflation. Earnings need to look for another.
I completely agree not everyone have this much savings and that return is not enough to support life. But he didnt mention anywhere how much he has for investing. And for steady income
without doing anything, i find this as best possible way with less risk. Else jobs are best for option of steady income.
