Definitely the major source of money comes from my daily job and it is not a lot of money but I really glad that early understood that investments it is absolutely important. When I was talking with my friends or colleagues I realize that a small amount of them invest money in assets. Especially they don't think about financial independence and often buy unnecessary things.
Obviously it is a waste when we only spend money on something or goods that are not needed, but when we can think for the long term or for the future then indeed, investment is the main thing to spend your money. So in this case I don't think money from anywhere will be a problem as long as you get the money in a good way to invest, because the thing to worry about is when someone invests from dirty money.
I have source investment money from my job, I working hard every day and save my money to invest with bitcoin, after reach more than 2004 with working a month I use for investing with bitcoin and hope my can increase my money at the future, I pass with many time profit and lost with my bitcoin and altcoin investing and keep working again if my investing have lost.
