You can own part of a Bitcoin. Like, it's not an all or nothing. It could be divided way, way, way down, like, to a millionth of a Bitcoins. Even if you buy this stuff, there's no sure thing about you actually earning those Bitcoins. People are starting to treat it more like accumulation of wealth that they don't then liquefy. They just keep trying to accumulate money even though everyone's valuing it so highly because there's no exchange happening. So yeah, what are some of the disadvantages or things people should watch out for? Then what are we buying with this stuff? Excellent questions.
