Hello, I am glad that you have paid attention to my book. I’ve been working in the field of fraud prevention and risk control since 2008 and started my career with banks in card issuing and acquiring. After that, I continued working in the field of e-commerce in payment aggregators, including cryptocurrency ones. I’ve gained experience that I’d like to share in this book.
