There are many people who think Bitcoin is a scam that is why Bitcoin is not implemented everywhere but those who know about Bitcoin are accepting Bitcoin as a national currency. In that case, Salvador. They keep a lot of Bitcoin in reserve for their country for inflation protection and financial security.
That's already changing, el Salvador cares about Bitcoin, if it's scam they will be the first to have abandoned bitcoin, if that wasn't enough, president of the United states starts talking about Bitcoin, putting his family into the innovation.
If Bitcoin was a scam it will never happen, how about BlackRock and others? They don't associate with scams, the truth is millions of people are so dumb to see things clearly, until it's too late, this is who they are.
It took me a big figure to want more Bitcoin, John MCAfee for example, followed by Kiyosaki, I wasn't even expecting the president of the most popular country to support Bitcoin.
It shows that no matter how far this thing goes, many people will always remain the same old fashioned.
