Chainanalysis just posted a thorough report on crypto crimes in 2019. From dark web to scams to hacking, they summarize the numbers for all of it. https://go.chainalysis.com/rs/503-FAP-074/images/2020-Crypto-Crime-Report.pdf Scams were by far the highest category. The report covers money laundering and a host of other criminal activity. Long read, but worth at least a skim.imwas surprised scams were higher in 2019 than in 2017-18. It felt like they peaked during the market crash of 2018, and probably caused it. But the graph for mid-2019 dispels my personal guess on that.
