      Then find me a coffee shop that will let me buy an espresso with Bitcoin.

      There are none. The transaction costs are larger than the cost of a cup of espresso. No one sane would do it any more. There were places that _did_ do it back before the transaction costs spiked through the roof.

      In fact, years ago, I could in fact have bought lunch in NYC with bitcoin without much trouble, but once people started getting interested, the limited transaction rate and high transaction costs made that collapse.

      You might of course find someone willing to do it as a stunt, but if they did it every day, they would lose money. The number of merchants accepting bitcoin is radically *lower* than it was in the past, not higher.

      I have a friend who made a scalable cryptocurrency protocol which should have solved this problem, but investors said nobody was interested in new currencies any more, only stuff built on top of old ones.

      I don't see why a novel cryptocurrency should be harder to start now than 5 years ago though; if Bitcoin etc. aren't being used as a medium of exchange, then the "market" for a medium of exchange is no more competitive now than it was then.
