The industry of selling information is not very high, but it is illegal, profiteering a lot of them will touch the law, the risk is high, if you are not careful, you may also be arrested, so really do not go to these roads to get wealth, because it is really very dangerous, you want to think about it, is the life of the important or the money is important, so want to get wealth through these, hurry up!
But there are some professions that are quite lucrative and profitable but not illegal. Fish tank cleaning and ornamental fish treatment average profit margins of about 800%, in the aquarium market at the top of the list, an investment of more than 100,000 yuan store annual earnings of up to 60,000 or 70,000 yuan, the good can be up to a million dollars. But in the aquarium market, this kind of store is not conspicuous.
In fact, this industry would have had a larger profit, most of the items are probably more than 300%. And the profit on medicines is even higher than 1000%. The same bottle of gentamicin is sold for a few cents at a regular drugstore, while it can be sold for up to ten dollars when used to treat fish. Similar situations abound. The technical components included in the service can be considered zero cost, and charging hundreds or thousands of dollars at a time is almost always a pure profit.
Secondly, the demand is relatively high. Now many people love to raise fish at home, but ornamental fish also called "rich fish", because they are too "pampered". Fish tank water quality is not good, outside interference or stimulation, improper feeding will cause fish disease leading to death. But to maintain the aquarium, after the moss and scale, wash sand, repair water plants, clear the filter, and repeatedly pumping water to add water and a whole set of procedures, the average person not only will not be this expertise, and do not have the time. For the fish treatment, the vast majority of fish people do not know.
