My favorite future use case is electronic cash with privacy. There are many LEGAL activities that people do not want to show up in a central database. For example, think of many things related to love and relationships. "tantamount to waiting for a greater fool to buy out the current players" <= this is like investing works in general, or? ;-)

> many LEGAL activities that people do not want to show up in a central database Unfortunately cryptocurrencies aren't just a central database they're a distributed database - all transactions are public. You can try using a tumbler service but since these are obviously money laundering havens they're not going to last long.

  Monero, Zcash, Grin. Three designs that are based on different cryptography - all three giving user full privacy.

  >all transactions are public Not the case, see payment channels.

There are also plenty of legal efforts (e.g. free political speech) that are actively being shut down by payment processors of all sorts; these need some means of sustainment and crypto has provided what is needed.
