Cryptos are definitely not mainstream. I'm from Kenya, Africa and the other day I tried to talk about bitcoin in some facebook group and most guys shut me down with words like

It's a pyramid scheme<<
It's an MLM<<
It's been banned by the Central bank so it's illegal...<<
I was shocked at the responses. This just tells us that the cryptoworld is nowhere near mainstream. And I intend to play a part in making it mainstream by spreading the word everyday on my facebook page.
