There is no single person on earth who haven't heard of bitcoin.
Everyone is talking about it, it's all over the news, everyone is buying it, price is dramatically increasing.
It's like gold rush back in 1848.
So why aren't we calling this bitcoin rush?
You know, in 20 years from now it would be funny to say - yeah, i bought/mined bitcoin during bitcoin rush back in 2017

I am not quite sure about what your saying. Tho bitcoin is now known about the fact that it kinda rushes money, it is still not really famous or known. Maybe in some countries they are that patronise. In our country, it may not be that famous at the same time not that limited for us.
