The government and many people are lying in order to mislead many people to choose their centralized money and investment which they have full control over it. If they tell a good thing about Bitcoin to everyone, most people might abandon fiat and choose to store their wealth in Bitcoin, it will make the banks fail since lack of liquidity and they will make a lot profit.
But thanks to this forum where many people will not mislead you about Bitcoin, even someone would give a wrong information, there's someone will correct it.
I think that what happens to most countries because the government tries to maintain control over the financial system and prevent the rise of a competing currency. And we can't deny it, some government officials do not fully understand Bitcoin and its potential benefits, leading them to be skeptical or even opposed to it. They associate it with criminal activities such as money laundering and terrorism financing as if they haven't done it themselves. As bitcoin threatens banks, maybe the governments are protecting the interests of these institutions by lying about Bitcoin and discouraging its use.
I think they just don't encourage the people to dive into the bitcoin world because of its decentralized feature. If in case one get scammed or anything, they don't want to take accountability of it because it is not government driven. But these don't help. They should provide factual info about bitcoin's benefits just as how much they provide cautiousness about it.
We are all being feed of wrong information of economic norms by the billionaires that benefiting the current system. Bitcoin is the best asset to invest in terms of price growth on long term period yet people are still scared to touch due the wrong information given by the main stream media.
In the country that I live, Bitcoin has a stigma of being a scam because our own government warn the public to not engage on Bitcoin investment due to a lot of scam involves it and the volatility is high. Most of the people here including the old professional don’t dare to touch it despite Bitcoin already has good price history.
In my country, we have somewhat mixed stance on Bitcoin and other cryptocurrencies. Our government has not banned the use of cryptocurrencies, but there have been some regulatory issues and concerns. Our central bank issued regulations that required virtual currency exchanges to register with the central bank as remittance and transfer companies but of course not everyone complies. And it's difficult to trace people who have to register since bitcoin is a decentralized system. They also issued a statement warning the public about the risks of investing in cryptocurrencies, stating that they are not backed by any government which I think just created fear towards investing in Bitcoin.
It is really our responsibility to educate ourselves. We cannot rely solely on what the government feed to us They lie too, most of the time.
