I believe this is why ethereum was so popular, as it introduced the idea of "Smart contracts". So the transaction is dependent on something occurring in the real world. Obviously there have been a ton of developments since then with newer crypto currencies, including increased privacy, anonymity, linking to applications, etc. For instance, I think Chainlink rewards people for hosting datasets (like ML datasets, or waybackmachine) on ipfs, and also inherits the smart contracts from ETH. Additionally, I think Monero has made developments in smart contracts as well, and the price seems to be more steady, since people actually seem to be utilizing it more for buying things in the real world, like computer services and such.
