Leonard Peterson

I trace stolen cryptocurrency and build the evidence needed to do something about it.

My background is finance rather than policing. I read finance and business at Stockholm University, graduating in 2010, and hold a master’s degree from Imperial College London, completed in 2012.

I have worked continuously since 2010 — sixteen years, the first two of them alongside the master’s.

That background shapes how I work. Cryptocurrency fraud is a financial crime that happens to use an unfamiliar ledger. The tracing is technical, but the case is built the way any financial investigation is built: reconstruct the flows, identify the counterparties, document the method, and be honest about the limits of what the evidence shows.

I work in English, Swedish and Finnish, and take instructions from clients in the United States, Canada, the United Kingdom, the European Union, Switzerland, Norway, Australia and Singapore.
