You can get passive earning by investing in shares. Or maybe real estate somwhere at good location where is big demand so the value is rising. Or from valuable watches, jewlery, art, gold. Bitcoin could be also source of passive income if you have invested it somwhere or maybe just by holding it and waiting for price to go up.
No not agree with you these source can not be source of passive income, these source can be investment source but can's be passive income source. Getting a real job or a business income e.g. regular income from a shop can be passive income.
I can see you two have two opposite opinions over there, and I'm afraid I can't agree with you. A job or a shop usually brings to you an ordinary life, nothing special. Investing in shares, real estate, gold,... are common ways to get rich, and works for lots of people. I personally believe in bitcoin too.
"Getting a Real Job" itself means you are working for you to earn money. Having a real job is not a passive income rather it is a main source of income. Let us not confuse ourselves with simple terms. A passive income is a source of income in which it generates revenue without your everyday work. Passive income such as interest or bond payments are good source of passive income.
