No body in quote can cap Bitcoin price exactly, it has to be on basis of speculation within a specific period and as long Bitcoin utility continues, the price of Bitcoin will always make new ATH. Bitcoin price is speculative not definite.
Bitcoin is already popular now, but I believe more and more people will learn about it and invest in it in the future. This will give Bitcoin the potential for significant price increases. Considering inflation and average growth, I even believe Bitcoin will reach one million dollars in the next five or ten years. Given its current valuation, it would surpass gold's market capitalization, but I also believe gold will remain the world's largest asset by market capitalization in the future. Since Bitcoin reached its new all-time high this year, I've become even more confident in its future potential. I used to be skeptical that Bitcoin would ever reach one hundred thousand dollars.
