There is no shortage of animals roaming about in RDR 2. If you can kill and skin your catch, you can take the meat to butchers to sell. It's not a good idea to ride around with your catch stowed on your house for long periods of time. Meat in RDR 2 can go bad. The longer it takes you to deliver the catch to the butcher, the less you'll receive in payment.
Once you have a little bit of money, you need to start investing it. The goal, of course, is to turn your investments into a passive income stream that will pay you for the rest of your life. It doesn't take much to get started. You can get started investing with as little as $1 with these free investing apps. Then, add another $100 each month and you'll grow your nest egg into something powerful.
Websites like Survey Junkie will pay you a decent chunk of change for the low-maintenance, borderline mindless task of completing surveys. Companies want to understand consumers better, and one way they do that is by compensating survey-takers (a.k.a. you). Most surveys pay between $0.50 and $1.25, and many of them take less than 5 minutes to do. You can read our full Survey Junkie review for more info.
