Bitcoin was launched in 2007. It's 10 years and still no country has approved Bitcoin ?? 
and in 2018, 2nd richest man "Warren Buffet" said "bitcoin will end up badly"
there are lot of country accept or approve bitcoin already. saying bitcoin will end badly is very wrong or fake news, 2018 will be a good time for selling coin but bitcoin will never die. bitcoin has lot of potential in terms of demand and its use, thats why people going to buy more coin this year. hoping that the price will increase rapidly again this year.and in 2018, 2nd richest man "Warren Buffet" said "bitcoin will end up badly"
