Go around the world and destroy every single mining hardware and every single device running a Bitcoin full node. Best of luck.
Bitcoin Nodes are irrelevant, as they can't add blocks without the ASICS.
Warehouse of ASICS are easily detected thru their massive energy consumption by energy utilities.
If the world governments agree, all they have to do is cut the power to those warehouses , and you have a bunch of paperweights.
Bitcoin Network freezes and enters a financial death spiral , as without the ability to transact, it market price falls below zero.
Therefore no financial incentive to save btc.BTC biggest security risk , is it can't hide the asics due to their energy waste footprint.
BTC supporters all cry fud about the energy waste.
So don't expect them to do anything to fix that security vulnerability.
Just watch for it to happen one day in the not so distant future.
By the time it does happen, every other crypto will have switched to PoS, and for them it will be a non-issue.
As their staking nodes are able to add new blocks and they can hide from the world governments, if required.
But since they don't collapse power grids, odds are they will be left alone.
