Which of the following is NOT a method of terrorist financing?

Real estate investment is a legitimate financial activity and is not inherently a method of terrorist financing. It is primarily a means of generating income through property ownership or development. While it is possible for funds from illicit activities to be funneled into real estate as a way to launder money, the investment itself is a common practice among individuals and businesses for wealth accumulation and financial growth.

In contrast, cryptocurrency has gained attention for its potential use in financing terrorism due to its anonymity and global reach, allowing for untraceable transactions. Charity organizations can also be exploited by terrorist groups to funnel money under the guise of legitimate donations. Similarly, smuggling and exporting equipment can directly involve illegal activities that support terrorism through the acquisition of weapons or supplies without detection. Each of these methods carries a higher risk of being associated with financing terrorism when compared to the relative legitimacy and standard practice of real estate investment.
