:)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"

It is a very tricky statement wherein the country will accept cryptocurrencies while accept its pros and cons.
Fortunately, such streak was ended when El Salvador accepted BTC as a form of legal tender on their country. With that in mind, it opens opportunities for cryptocurrencies to be acknowledged worldwide. Though its implementation might be far into the future, all of its effects are slowly experiencing by many due to its potential of either being a short or long-term investment.
Lets put up some link for reference:
https://www.nytimes.com/2021/09/07/world/americas/el-salvador-bitcoin.htmlLots had really believed out that it couldnt really be possible but El salvador did really make this thing to happen and never ever we did really expect for this thing to happen.
Those presumptions and anticipations that we do have in the past did really happen on this moment and of course there are cons and pros that we've seen
but doesnt mean that they would stop on.
