Running your own node is not to protect bitcoin network but to protect yourself

Happy Christmas everyone!
I see some confusion in the Bitcoin community, and wanted to help clarify this. I do own and run my own node and I’m happy with it. But I’m also a miner and I do know that my node is not what protect the network but the mining power is.
Getting 51% of nodes is not that hard to do, there is about 50K nodes, so let’s say 1TB per node so it is about 50PB, which is nothing for a single small-medium company with an enterprise setup.
That’s why for a 51 % attack you need mining power not nodes. Right now the hashrate is about 177 EH/s according to my umbrel node. So you may need about 90 EH/s with the power and equipment of a whole country to just try a double spend, a.k.a 51% attack, see more here: [https://www.investopedia.com/terms/1/51-attack.asp](https://www.investopedia.com/terms/1/51-attack.asp)
And don’t get me wrong, Like many said here before, running your own full node is a wonderful thing, not to protect the network per se but to protect yourself. *Don’t trust, verify.*
Btw, if you want to protect the network, after the move of miners out of China ban there is a lot of opportunities, check [https://www.asicminervalue.com/](https://www.asicminervalue.com/) and you can also be a miner as well, an Antiner S17 or S19 is about 5-10K USD and can do 80-100TH/s, you can join the pool of your preference and get your mined bitcoin with minimal fees.
