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.

Roles and employers across those sixteen years, in two to three sentences. The dates above establish that there is no gap; this is what says what was actually done in it, and it is the single most scrutinised paragraph on the site.

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.
