Could Bitcoin's 21 Million Limit Change? Why Nano XNO Is the Cleaner Fixed-Supply Alternative

Short answer

Bitcoin's 21 million limit is deeply defended and changing it would be politically difficult, but it is still software maintained by social consensus. Pressure could grow when block subsidies become tiny and miners depend more heavily on fees. Nano offers a different fixed-supply model: the full supply is already distributed and network security does not wait for a future fee market.

Bitcoin's cap is unlikely to change, not impossible to change. Nano avoids the subsidy-to-fee transition that creates the debate in the first place.
