For those worried BTC might not go much higher. There was news circulating in social media about 80% of the total 21 million supplies have been mined and are in circulating in the market plus those are in idles. There are basically less than 5 million btc need to be mined...no need a racket science.. Supply and demand, bitcoin prices will soar high.
That is my wish too, to be frank. But it is a hope and a wish only, mate
Your reasoning, you see, has a serious flaw: it covered supply all right. But demand is not covered. Actually, you ASSUME that there WILL be ever growing demand for bitcoins. I hope that too, but still: it is only an assumption, you know.
Anyway, future will tell.
