I think this is ordinary. Everything new goes through the stage of birth, the stage of development. stage of triumph. death stage. Before the stage of triumph is still far away.
I don't think that this is the end of bitcoin, because until now bitcoin is still on top even though the value/price is dumping it can always rise up just like what happen last year. I agree to your opinion that this is ordinary and I think bitcoin's end stage is not yet exist but when it does, bitcoin had so many contribution on the world economy.
