I don't know, but im sure if the price of this is not over 500 usd in the next 2 years, then it will be less than 20 usd or even 10 at that time.
Lol... Yup, it will be over USD 500 in the next 2 years.
So the second part of your sentence is really unnecessary.
I think they're paraphrasing Satoshi:
Quote
Im sure that in 20 years there will either be very large (bitcoin) transaction volume or no volume.
(Feb. 14, 2010)
Yes, they seem to be.
Only thing is they have shortened the 20 year time frame to 2 years.
15 years (time's moved since Satoshi said that). And (not unreasonably) extrapolating price from transaction volume. But if we're to see "no volume" in 15 years we'd presumably expect to see a trend toward that, rather than transaction volume and price suddenly hitting zero.
