The people that knows how Bitcoin works will not buy the lies because of the knowledge. But because of the fluctuation in rates/prices, it's easy to tell the lie because nobody wants to lose the money invested.
In my opinion, many see Bitcoin as gambling because of its volatility and I think these narratives need to be changed also I want to believe that Bitcoin is a threat to banks, with this, the banks will want to spread negative news to the government and citizens. The bank's concerns and fears aren't now but the future.
@initim, It's not only about people who know about Bitcoin already, it also concerns those who have the desire to venture into Bitcoin, but after hearing those economic lies about Bitcoin, they end up having some misconceptions about Bitcoin that can kill their desire to invest again. So it doesn't only concern the already-existing bitcoiners.
Despite the fact that some people see crypto as gambling, the fact remains that there are a lot of cryptocurrencies in the crypto market, and due to the fraud issues that some crypto beginners have experienced with some altcoins, they just conclude that the entire crypto market is a scam, or some say it's gambling.
For someone who has not even had any experience with cryptocurrency to say crypto or bitcoin investment is gambling, that means they have gained the wrong information, either from some economic lies, as the OP has said.
If you talked about price and volatility, that has been the nature of Bitcoin for a long time now; the market always fluctuates, which even gives individuals the possibility of buying at a low price and making profit when the price is bullish again.
The only challenge some people are having is that they rely on spoon-fed information; as such, they don't do some research themselves to gather the information they want, so they can be mislead with any wrong information they get. So, if we by chance come across this kind of person, we should explain to them and make them understand how Bitcoin works instead of leaving them in their misconceptions.
