It's still a decent method for people who don't yet have a goldfish farm. Of course, once you do have a goldfish farm, you'll realize it's much easier. 2 goldfish statues + crab engine = a stack of goldfish in 17 seconds. That's a profit rate of 2 gold coins / 17 seconds, which translates to a platinum coin in about 14 minutes. Once set up, all you have to do is stand by the fish statues and collect the goldfish, then sell them. See Wire Creations for more details.
