The best way to earn money is of course passive income. This is money which you earn by doing nothing - such as interest on money in the bank. I consider any paid advertising to be passive income - things such as banner ads and text links which earn me a monthly income. It would be great to have more passive income and I have been thinking about how to get it.
I consider earnings I get through referrals to be passive income. Once I have that referral then the money comes in with me doing nothing. I have therefore been wondering whether to buy some more referrals for Bux.to. I have made a profit so far from upgrading my membership and buying referrals. The only disadvantage is the amount of time they take to pay. I have decided to wait until I get my next payment from them and then consider what to do.
