So long as the mempool is crowded and fees are high, bitcoin isn't dying. Lack of usage is what kills things. I do agree with your underlying sentiment that more emphasis should be placed on using BTC as a currency and not an investment.
Eventually, the price will level out and it will become a investment that is as boring as gold.
I understand what you're saying here but do you really believe that bitcoin can be as boring as gold? I think bitcoin will always be more interesting as it is dynamic and capable of a lot of things gold isn't. As far as price volatility is concerned, gold has a several thousand year head start... not sure BTC will ever be as stable in price.
