Indeed I have, appearing later in this thread due to how it became organized by moderation. Digital assets aided in stopping a predatory crime this year. If this kind of usage doesn't satisfy as a rebuttal to a negative parent post containing no supporting information, you may want to examine the fact that this entire thread is meant to explore some technologist's fear-based need to publicly associate digital assets with crime alone, in this forum especially. Emotionally-driven posts meant specifically to steam-roll any and all positive discussion by simply shouting "But Crime!"
Tracking the making of negative generalized statements using FUD techniques is something I have been involved in algorithmically tracking professionally and am countering not in the pursuit of karma or sycophantic agreement but simple public commons maintenance. (The data was often used to identify FUD campaigns of short sellers in finance forums and resulting sentiment analysis feeds are available via subscription through financial data providers.) These comments never mention the continual reigning supremacy of the US dollar for crime, ever, and never provide any evidence that bitcoin has a higher crime usage ratio than the dollar with less prosecutability. This is because law enforcement generally haven't advanced that position while enforcing and in earlier posts I've explained my extensive experience in detail as to how and why they haven't. There has been no direct engagement with this factual information.
In my view some on this forum are intent on spreading classical FUD on the subject and countering FUD is an occupation for some. After a decade of particularly questionable behavior coming from the technology sector involving unfathomable amounts of US dollars, we run the risk of portraying an image of incumbent ideological corruption instead of supporting meaningful technological discussion. This slide has been happening for years IMO and it saddens me. Younger technologists have considerably less opportunity than we did, not more, and the frontier is much smaller. Ruthless negativism doesn't serve them.
