In the realm of cryptocurrency and finance, the Howey Test serves as a critical framework for evaluating whether a transaction constitutes an investment contract, thereby falling under the purview of securities regulation. However, the intricacies of this test often leave many with questions. Could you elaborate on the four fundamental questions that constitute the Howey Test? Specifically, I'm curious to understand: First, is there an investment of money? Second, is there a common enterprise? Third, is there an expectation of profits?
