Answer:A get-rich-quick scheme is a plan to obtain high rates of return for a small investment. The term "get rich quick" has been used to describe shady investments since at least the early 20th century.[1][2]
Explanation: Most schemes create an impression that participants can obtain this high rate of return with little risk, and with little skill, effort, or time. Get-rich-quick schemes often assert that wealth can be obtained by working at home. Legal and quasi-legal get-rich-quick schemes are frequently advertised on infomercials and in magazines and newspapers. Illegal schemes or scams are often advertised through spam or cold calling. Some forms of advertising for these schemes market books or compact discs about getting rich quick rather than asking participants to invest directly in a concrete scheme.
