Begin Cryptocurrency Related Financial Crime Investigations and Move Them Forward with Confidence

My name is Larry Nielsen. I am an active law enforcement Detective in South Florida USA. I have over 17 years of experience in law enforcement and over 7 years of experience as a Financial Crimes Detective. I am also a cryptocurrency investor and and NFT creator and collector. I enjoy tracing cryptocurrency and non-fungible token transactions across the blockchain!

With the rise in popularity of blockchain, cryptocurrency, and NFTs also comes the increase in related crimes and the urgent need to know how to investigate them. The objective of this online/on-demand course is to provide you with solid foundation and practical, usable investigative techniques that you can benefit from daily.

I created my flagship course, Blockchain Basics + Cryptocurrency & Non-Fungible Token Transaction Tracing for Investigators aka the Crypto Course for Cops, and have been teaching an in-person version since the beginning of 2022 in the USA and have now transitioned it to an online/on-demand format to be able to reach more investigators. I have added so much more value to this online/on-demand version and it is now open for registration!

This course starts by teaching you the basics about crypto and blockchain, walking you through investigative considerations, and progresses to YOU tracing cryptocurrency transactions and a non-fungible token transaction across the blockchain!

Below is a video snippet of transaction tracing that YOU WILL DO in my flagship course. This is ONE of the ELEVEN different transaction tracing exercises that you will work through across SIX different blockchains using SEVEN different free and open-source blockchain explorers.


Testimonial from a Detective who attended my in-person version of this course in Salt Lake City, UT:

"I attended Larry Nielsen’s FinTech Crypto Tracing course in March 2023. Since learning the basics of crypto tracing from his class, I have had much success tracing and seizing crypto funds.

In the past few months, I have seized about $50,000 USD in crypto from all over the world. I’ve also created crypto investigations policy and a government-controlled wallet account for our Department with information obtained from Larry’s course.

I highly recommend this course for any investigator looking to expand their financial cases into cryptocurrency."

About my new focused breakout course; Tracing Ethereum/ERC20 Tokens Through a DEX to a CEX


You've made a great choice making your way to this page!

This is the registration/purchase page for my specialized online/on-demand training course, Tracing Ethereum / ERC20 Tokens Through a Decentralized Cryptocurrency Exchange (DEX) to a Centralized Cryptocurrency Exchange (CEX).

In this course, you will learn and actually practice a skill that few people possess.

In many cases, bad guys will steal cryptocurrency or scam the victims out of it, move it to a non-custodial wallet address and then swap it via a Decentralized Cryptocurrency Exchange (DEX) before moving it on from there. Even the investigators who have a basic understanding of cryptocurrency transaction tracing, often find themselves stuck when they see the cryptocurrency is sent through a Decentralized Cryptocurrency Exchange (DEX). Even when using some paid advanced blockchain analytics software, when tracing shows the use of a DEX, there are many times that investigators would need to know how to jump back into manual open-source tracing in order to continue.

Well, in this course, I am going to empower you with the knowledge, experience, and ability to keep tracing even when you see the use of a DEX.

This course content is also included in my FLAGSHIP course; Blockchain Basics + Cryptocurrency/Non-Fungible Token (NFT) Transaction Tracing for Investigators.

The course you are about to register for is shorter and focused on the specialized topic (pulled from my flagship course) of tracing through a Decentralized Exchange in the Ethereum blockchain. I found that a lot of people were interested in this specific topic so I created this break-out course to address it specifically. After taking this course, you will be offered an Alumni discount on the full course should you wish to take that as well.

In this specialized focused online/on-demand training course, you will trace stolen cryptocurrency and ERC-20 tokens across the Ethereum blockchain through non-custodial cryptocurrency wallets, through Decentralized Cryptocurrency Exchanges (DEX) where the bad guy swaps them either from ERC20 tokens to Ethereum or from Ethereum (ETH) to an ERC20 Token and then through non-custodial wallet addresses and ultimately to a Centralized Cryptocurrency Exchange (CEX).

Both tracing exercises have detailed written walkthroughs with screenshots plus video walk throughs so you will understand what you are doing and why you are doing it.

After each tracing exercise, there is an accompanying lesson where you will learn how to document the tracing that you just completed.

You will also get a BONUS lesson teaching you how to use a powerful free tool inside of the open-source blockchain explorer that you will already be using to trace in this course.

The course also covers some of the basics of cryptocurrency and blockchain plus important relevant vocabulary.

SPOILER ALERT: This course is not all inclusive. You will learn a new and very valuable skill here. However, once you begin your cryptocurrency transaction tracing journey you will encounter things not covered in this course. That's how the cryptocurrency space is. Beware of anyone who sells a course with the promise of it being "the only course you need" because that just isn't true.

Once you get this specialized foundational knowledge and experience, however, it will make understanding other tracing situations that you encounter much easier.

Once you register and pay for this course you will have full access for 30 days. You will complete the course quicker than that but I want you to be able to go back over it more than once if you would like to get more practice.

After completion, your certificate of completion will be auto generated using the name that you registered with so make sure it's the name that you want on the certificate. The certificate will then be emailed to the email address that you registered with.

Most importantly, once you gain these skills and get this experience, no one can take it away from you.

You can keep building from there.

Testimonial from a Detective Sergeant who attended my in-person version of my training in South Florida:

"I recently attended a block of Cryptocurrency Investigations training instructed by Larry. I’ve sat through several presentations over the years on this topic and never left feeling any more knowledgeable about the subject.

The cryptocurrency world is replete with its own language, much of which is unique to the crypto industry.

Larry has a way of explaining the terms in an understandable way that is relatable to daily life. His instruction was able to remove the veil of mystery and confusion surrounding cryptocurrency and the investigative process and left me and my team feeling more confident and capable of diving into these types of cases."
