weird price claim. it managed 20 grand based on the usual suspects. so he's saying if it infiltrates every market and attracts every potential buyer it's gonna double from there? that doesn't seem very realistic or ambitious to me. we're probably at 5-10% of market saturation right now and that might be massively overstating it.
I guess he wanted to make a prediction that can come true in the next few years, even regardless of Bitcoin's mass adoption, because $40,000 can be achieved through speculation and some adoption. $40k in 10 years should be ridiculously small of Bitcoin, since emission will be very low and its technology would be hugely improved. He is probably still considering a scenario where Bitcoin gets outlawed and can't get mass adoption and trading volume to sustain big prices.
It is easy for the price to be $40k in 5 years. But it is difficult in 1 year.
