A lottery ticket may be a reasonable facsimile, since it's not any kind of working capital or hedge mechanism that I can determine. It's an electronic fiat form of "cash" that people play with. But since it can't be invested and put to work, and isn't represented by anything real like gold or something else, it's only value is that it's scarce and hard to produce, hence it's "value". I think if you enjoy gambling and have disposable income to do so, it could be fun. But how many people have sold their bitcoin and retired multi-millionaires ? Serious question.
