The discussion centers around the fate of bitcoins acquired by drug cartels and hackers, questioning whether they convert these assets into gold or cash through laundering methods. Bitcoin's fungibility is noted, suggesting it could serve as an effective laundering tool despite public transaction records, as tracing ownership can be complex. Participants express skepticism about bitcoin's long-term viability, comparing it to historical fads like Beanie Babies and tulip bulbs, while acknowledging its finite supply and energy-intensive mining process. The conversation also touches on the speculative nature of bitcoin's value, its volatility, and its limited utility as a currency, with some arguing that it primarily serves as a medium of exchange rather than a stable store of value. Concerns are raised about the potential for quantum computing to undermine bitcoin's cryptography and the emergence of superior cryptocurrencies. Overall, the thread reflects a mix of caution and curiosity about bitcoin's future in the context of illegal activities and market dynamics.
