At this moment, I do not believe we have true decentralization. For me, true decentralization would mean no mining data centers are needed, and all calculations are distributed across mobile phones. There are some attempts, like Pi Network or Monero, but they still have limitations.
If a government backs a specific crypto, it could further centralize control, even if the technology itself remains decentralized.
While a state-backed crypto might bring legitimacy and adoption, it’s unlikely to align with the original vision of full decentralization.
