Here is my dream vision for crypto for coming years:
Decoupling geography and politics from finance:
People in every geography gets access to same currencies and a transparent credit market. Those who are unbanked gets access to same financial infrastructure on chain. People can collaborate with anyone across the globe and can be easily (without excess fees and within time bounds) paid for their work.
People can pay for things as trivial as coffee using their mobile wallets. Apps or devices can transact with other apps and devices directly to provide better service to end users. For example my router should be able to pay my internet service provider for extra bandwidth if I have exploited the bandwidth quota for the month.
With all the transaction online on public blockchains we also make the users vulnerable to surveillance by state or large organisation who may use that data in a way that users might not like. Privacy technologies like snarks/starks/bulletproofs becomes more user friendly and gets highly adopted. Users also may optionally sell or donate their data for the purpose for analysis but there is no tracking by default.
