A critical bug in Bitcoin Core 30, where a forced wallet migration can delete wallet data, underlines Bitcoin’s greatest risk today. It is not external attackers or quantum computing. It is developer error introduced through unnecessary change in the reference implementation. Bitcoin’s strength comes from stability and predictability. To seriously challenge central banking, the base layer must ossify. Every new feature, migration, or internal refactor increases the attack surface and raises the probability of catastrophic failure, even when the intent is good. To quote Michael Dunworth "This is not a calendar app you are fucking with, this is money"
