I didn't state any facts. I started with "I bet" and included "must be". Those are pretty clear opinion markers.
Your reply is also confused. Is the majority of money laundering denominated in USD and other real currencies? I'd believe it, because that's where the money is. But I'm saying the proportion of Bitcoin transactions that are fincrime-related is surely much higher than that of total USD transactions.
This seems pretty obvious to me given that Bitcoin is much less useful for quotidian transactions, but much more useful to people engaged in assorted financial crime. That's unsurprising given how much cryptocurrency advocates tout privacy/anonymity as features. But if you think otherwise, feel free to show the data that has convinced you otherwise.
Also, it's bad form to read something, go on a rant, and then declare the conversation over. Especially when the rant is incorrect.
