Yeah, if you read my first reply from where he quoted me,  then you would have a better understanding of what I was really talking about. Bitcoin can help expands ones income, but it's not what makes you think of expanding your income in the first place, because even before you decide to invest in Bitcoin, you already have that desire to make more wealth before you invest. So by assuming and believing that if you invest in Bitcoin, you will make a profit in the bull market, you can use the profit to do other investment.

For example, you are earning $500 per month, and you, being so desirous of more sources of income, decided to invest $200 every month until you have invested about $8,000, and let's say during the bull market, you made a profit of $8000, so you decide to take out $4,000 and invest in real estate or some landed properties. Short story short, you already had plans for expanding your wealth even before you invested in Bitcoin (that's were the argument started).
