1. Pure stupidity of crypto markets i.e. anything is possible. e.g. Verge could overtake BTC.
2. Tail reward comes to forefront as a confidence crisis over stability
3. On-chain fungibility advantage recognized as crucial
4. RandomX is a huge success (large and widely-distributed mining network becomes a clear advantage, contributing to a confidence flip)
5. Flexible blocksize results in significantly better on-chain scalability without a bloat explosion that destroys decentralization.
For 2 - 4, it's possible only if BTC's crazy pumps have really been cos of actual usage. But it isn't. The market is just one big, giant casino imo, so '1' is most likely.
Not so much. Most of it could easily happen just due to narrative and speculation. People can always convince themselves that "actual usage" will come later.
