:)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"

Well, that's because bitcoin is decentralized digital currency and every government has already their own currency. The important is, even government didn't approve bitcoin , it is still very useful and it also use as a source of income.
