It is said that Bitcoin may even fall to zero since it is not controlled by any centralised authority. Bitcoin is controlled by individuals in the node network meaning it is a musticomplex system where the transaction of buying and selling determines the growth of bitcoin.
How many centralized and custodial services have failed, yeah, countless. Ftx was controlled by a central authority and what happened, it was run to zero, to bankruptcy. BTC isn't going to collapse because it isn't controlled by a central authority.
Take note that there is nothing like the 'node network', any user in the BTC network can run their own BTC node, it is not made specially for any group of people, you can run your own full node and contribute to the network, and you don't control it by running a node.
