If Bitcoin someone and can destroy Bitcoin, then this is China. Although honestly, depending on how fast it grows, and the fact that China is not the only superpower in the world, I can say that Bitcoin's collapse will not happen.
It seems to me that bitcoins have become so widespread that nothing can completely destroy them. Of course, they can be undermined by a weak market situation, but they will not destroy it completely. The situation of bitcoins is constantly stabilizing, so I do not think it is possible.
