What are the chances of bitcoin going extinct?
IMO, the only way this can be possible is if the government shutdowns the Internet. Right from when Bitcoin started gaining recognition, the government has perceived it as a threat to traditional banking, so they've been doing everything possible to kill it. They've come at it with various sponsored political propaganda which turns to be futile. Now they've created their own clone Bitcoin (spot ETF) to compete with it. As long as Bitcoin keeps serving it purpose, it's going to be here for a long time.
That could be one contributes for its extinction but its impossible to happen since internet is so useful to all of us. But if this became a threat to financial system and government will tag or describe it as illegal currency which is used by criminals on their financial crimes then this could stir up everything and might we see bitcoin extinct for that reason since for sure powerful countries can influence other one so provably this thinking could possibly happen. But since the marketcap of bitcoin is huge so I think that one could change the mind of those officials and maybe they will look at other side and see how useful bitcoin on investment matter also for profitability if they take advantage of current condition of this coin.
