There are indeed aspects to the Bitcoin protocol that cannot be manipulated or changed:
  • Fixed supply: There will never be more than 21mm.
  • Immutable ledger: Transactions once validated under a few blocks cannot be double spent, changed, or deleted.
  • Consensus rules cannot be arbitrarily changed.
  • Decentralized: No single entity has control over the entire network.
Other PoW monetary systems like Wampum bead belts for example, used by Native Americans were not easily manipulated either. Not with the technology they had at the time. Trade worked for centuries with it. Gold could be diluted, but served humanity pretty well for millennia. I am bullish on the immutable properties of Bitcoin as well, but the price to fiat can, has, and will get manipulated.
