I expect you're right-- $10K (and beyond) is not far away.
It all has me wondering how (if) Bitcoin will even be able to establish itself as a "spending" currency. Why would someone buy loaves of bread with a "currency" that could double in value in the next 90 days? I wonder, sometimes, if that's one of the challenges faced by all cryptos, in terms if being publicly embraced on a large scale.
I'm not sure BTC will ever be a spending currency, there are many others that are better suited to coming into that role. As to the volatility in all of these, much is due to it still being a very small market. As the market heads to mass adoption much of that should smooth out.
