:)Bitcoin was launched in 2007. It's 12 years and still no country has approved Bitcoin ?? Huh
and in 2018, 2nd richest man "Warren Buffet" said "bitcoin will end up badly"

Bitcoin was created in 2009, not 2007. Warren Buffet said bitcoin would end up badly? That means he knows nothing he is saying, after his bad speeches and hatred for bitcoin, bitcoin has been surviving and more adopted.
Exactly. what Warren Buffet Said about bitcoin means nothing for bitcoin and blockchain. he has no idea what he was saying. he is not a tech guy. he himself admitted that he don't know how to use computer and the only computer he had was a old computer just for calculation purpose.
and I can list a dozens of other quotes From other known personally about Bitcoin and how blockchain technology is important for future.
