Work can provide you a steady income. Bitcoin and online jobs can help also but i am not yet trying to earn from bitcoin and other online jobs.
My steady income are from my work.
Also for me, I don't trust my income in trading for my daily expenses because it does not guarantee me to be profitable all the time.
I have a business and I earn regular income from it, but I am also a risk taker so I am trading and investing at the same time, but to make sure I can still survive even if I lose in trading I only spent a portion of my money, I am not a kind of person who loves to go all in.
i think not a single trading or investment can guarantee you that you must make money from there, but we only invest our money or do trading on expectation and always taking risk. because wee never sure about the profit about the trading or investment, we also work on our analysis and previous experience and skill which enable use to avoid lost and make some good profit.
