One of the best ways to earn money on Red Dead Redemption 2 Online is fishing. You can grind out some serious cash with fishing. Now there are many spots, this is one of my personal favorites. The Lake Sturgeon fetch $7.25 at the butcher, the spot I fish at is nice and close to the Rhodes butcher which makes running them back and forth convent. This spot is great use the River lure and fish away.
