Bitcoin is a revolutionary tool that enables all kinds of ideas and experiments, including this one. But that doesn’t mean it’s the main or most important path for Bitcoin adoption. Turning lost bets into systematic Bitcoin demand is an interesting concept on paper, but it’s still a secondary and relatively niche use case. The core value of Bitcoin remains elsewhere.
just because I want something doesn't mean I am actually going to use it. That's basical it. If casinos decided to actually use Bitcoin it won't create more adoption of Bitcoin than it's already has. I am saying this because buying, betting winning and then converting your coin to your fait currency doesn't mean adoption.
