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

Several individual are yet to hear about bitcoin,especially in developing countries,where internet facility is poor and not available in some cases
