I think that a real threat to Bitcoin could be that if prices keep rising and therefore mining being even more profitable and then many more people wanting to jump on that train and therefore starting to mine. This will lead to a massive energy usage that most countries wont be able to supply. Therefore governments sure will step in and maybe prohibit mining. As mining is something physical, its not that easy to do if its considered illegal. I think that this could become a real issue for Bitcoin and crypto in the future.
