Ethereum is one prominent example of this: we'll swap currency on your blockchain for currency on our blockchain, ours will totally be worth more due to enhanced features. They aren't making more numbers "We can conveniently restrict the supply of numbers" is one of the fundamental failures of the imagination among Bitcoin enthusiasts. "There's only 21 million. Trust us. We counted." "But couldn't I make a new 21 million with a one character code change?" "Well yeah but they'd be so much less cool than our 21 million and you'd have to convince people to use them." "But wouldn't I be able to use the Satoshi adoption strategy -- give them away for cheap to bootstrap a distributed boiler room then gradually make them more expensive, enriching early participants in the scheme at the expense of later participants?" "But that's crazy, it will never work. Nobody wants worthless currency units tied to a transaction network that provides absolutely no value. They want spendable money." "Of course people want worthless currency units tied to a transaction network that provides absolutely no value, if they have the expectation that they will not be the last people to want those currency units. That describes why you invested in Bitcoin!"
