It should be, but the cryptocurrency crowd have internalized Austrian deflationary bullshit as a premise for their money system, it's just doomed to be unused as a payment mechanism and keep being used as securities.
It's literally Economics illiteracy killing the use-case.
Interestingly enough, the fact that they are used as securities is also responsible for why bitcoin is still the biggest fish in the pond while being technically pretty meh and long obsolete (very long block time, no “smart contracts”, failed as a decentralized system because ASICs, etc.).
