Mehmet Aydın is a Turkish businessman known for founding the online investment platform Çiftlik Bank. Launched in 2016, this platform allowed users to invest in virtual farms and earn profits through livestock and agricultural products. However, it gained notoriety for being a Ponzi scheme, leading to significant financial losses for many investors. In 2018, Aydın fled Turkey amid investigations into Çiftlik Bank and was later arrested in Uruguay. His case highlighted issues related to online investment scams and the need for regulatory oversight in the digital economy, raising awareness about the risks associated with such platforms.
