I think a lot of haters do, they align the behavioural qualities of a ponzi scheme with Bitcoin by pointing out how the only way a unit of BTC can have value is by selling it forward to another person. Which is indeed a property of any money; if nobody wants it, it cannot have value. However, I'm not sure they've taken the time to think about what the real-time monetization of a newly discovered commodity looks like. It took gold thousands of years to become a global currency, and now we have something similar but with the speed of the internet. With the physical properties of the Bitcoin protocol / blockchain (halving, fixed supply, etc.), it starts to look very obvious as to why people want to front run it, or use it as a store of value. And so the expected behaviour becomes obvious.
