I believe we should have a discussion on why it's so important to defend the bitcoin network to the death.
(metaphorically speaking, we don't have to sacrifice any life.)
I don't think we need to exaggerate things here, bitcoin's network has been running a unprecedented 99% uptime if I'm not mistaken for the last 10 years or so. Meaning there are really people without getting incentives to keep the network secure.
And nodes will keep growing regardless, it is decentralised and this is one of bitcoin's strength and everyone knows this since the beginning. And it is not that it is going down a bit, so defend it to death is such a exaggeration.
i dont know where the OP got the idea of his statement. but yeah, theres no need to defend or anything because there's nothing to defend for in the first place. we can say that the btc network is relatively secure as there are people who are into this even without the request of the community.
or maybe the op meant defend the existence of btc to other nonbelievers? anyway, we cant push other people to believe in crypto or btc in particular, you can educate them but it is still up to them how they will use crypto in their lives. dont expect that they will embrace at the first time they will hear it. but only a matter of time before they realized whats their missing...
