In my humble estimation (based on my own scientific, engineering, economics education) as I am learning more about it, Bitcoin will reach valuation around $10,000 within 0-2 years (at the time of this writing it is already back up to around $8,000 rounding to the nearest thousand) and then will reach valuation $100,000 within 20-40 years and then $1,000,000 (each single Bitcoin) within 40-120 years of this year 2020. Today there are 17,000,000 Bitcoins in existence for around $170B (billion) market capitalization. In 2140 there will be 21,000,000 Bitcoins in existence. I am conservatively guessing the market cap will be around $2T-$20T (trillion). This is my own projection. Do others in the Bitcoin community (this forum) agree that my estimation or forecast is reasonable to expect? Clearly there will be huge or not so huge price/valuation changes or swings over time. There is no arguing that, however, over long term the starting data point of $10,000 around 2020 and $100,000 at around 2040-2060 I think are two reasonably expected data points. I will be 75 years old in 2040, so that will make my retirement years very happy (should I not get hit by a bus before then).
