This is a great article! I honestly had never even heard of some of these money-making methods (e.g., selling plasma, flipping domains, renting your car for ad space, etc.). While I would presume that there exist various risks associated with, say, plasma donation (which would explain why it is so little-known), many of the other methods seem relatively simple and, potentially, very lucrative. It’s kind of interesting that they’re not as well-known as some of the other methods listed despite their not having any apparent drawbacks (such as the ad space on one’s car). I guess the old saying that there is a job out there for everyone may, to some extent, actually be true.
