Bitcoin and the various imitators are the Beanie Babies of the 2010s. If you want to play that game, be aware that the bottom could fall out anytime and you could be left with zilch. They're laughably useless as currency for a variety of reasons *beyond* the fact that they have not been widely adopted, they're not anything like as anonymous and under-the-radar as they are made out to be, and 99% of them are bought/sold by people who have no intention of buying actual goods or services with them but are buying to later sell. Definition of a speculative bubble, no?
