It is not a simple work, people have to wake up early in the morning, be aware of thieves, work hard in the rivers and sell the gold.
There are also some people keen on search for gold in rivers during the week end. This is a sort of hobby, these people don't sell the booty, but collect every single piece of gold and categorize them all by: type, color, dimension, place of occurrence and date.
People keen on gold which spend them week end in these kind of search are completely different from the ones which were part of the gold rush in America during the early 20th century. The gold lovers of today are wealthy persons, more or less rich, able to buy equipments and tools to find out gold into the rivers! In the past the gold diggers were people of all the social classes and most of them were desperate people looking for a new life, more comfortable and wealth.
In the other hand today there are people which decide to became a gold digger to increase income and survive. There are persons which need to spend hours and days on the river because this is the only one way to earn something. Probable some of them don't know how much could be a wealthy person spend for 10 grams of gold.
