The exposure of Nigeria's CBEX platform Ponzi scheme can be quantified in several ways. Firstly, analyze the number of affected investors in Africa and globally. A sharp increase in complaints and inquiries to financial regulators indicates significant damage. Secondly, observe the decline in trading volume of local and global cryptocurrency exchanges, as nervous investors may withdraw. Thirdly, measure the drop in new investment inflows into African - based or related cryptocurrency projects. These metrics can reflect the extent of the blow to investment confidence.
