Bitcoin was launched in 2007. It's 10 years and still no country has approved Bitcoin ??
Uhh, bitcoin was officially launched in 2009, not 2007. Also, 2018-20017 is 11 years, bitcoin is only around for the last 9 years.
Japan is already a bitcoin-friendly country, with
fair regulations for bitcoin users, and if that isn't legalization or approval in your books, then I don't know what is.
and in 2018, 2nd richest man "Warren Buffet" said "bitcoin will end up badly"
Why would I believe on someone who made so much fiat and supports fiat in the first place? The reason why these billionaires are against bitcoin is because they know their assets would be in deep trouble if everyone and their mothers began shifting their assets into bitcoin and fiat would be left alone. For all we know, these billionaires might have bought their own share of bitcoin discreetly that's why it's okay for hem to constantly go against bitcoin and begin praising it once they've made a sizable profit in the end.
