It very sad to know that despite the amazing things bitcoin has done in the crypto space many are still doubting it to be scam. Not knowing it value and potential that can change there life completely.
Those who still think of Bitcoin as a scam coin actually have no plans to invest in Bitcoin, but rather they always discourage people from investing in Bitcoin. If Bitcoin was a scum project, many big stars, including the world's biggest entrepreneurs, President Donald Trump, EL Salvador president, would not have trusted Bitcoin. Moreover, some investors and countries are still investing in Bitcoin. However, if they do not have proper knowledge about Bitcoin, it is natural that they will always consider it as a scam project or coin.
It is very likely that their perspective is too narrow, for example many people see that they have experienced big losses in crypto without exploring it more deeply, for example the concept of this type of future trading is clearly different from the spot method system that many people use. And many people don't understand how blockchain technology and cryptocurrencies work, so they tend to think of them as something untrustworthy (intangible) or high risk.
In my opinion, as time goes by and prices are now quite high, they should be able to realize this and there is a lot of news in various media such as television which often reports on this asset. And many institutions or countries as you said above and as we know more and more large companies can accept this asset as a payment method. If anyone still says that Bitcoin is a fraudulent asset, in my opinion just ignore it, why are we telling people to invest here as if we are enriching their finances.
It is indeed better that we never postpone it, and to continue accumulating this asset, the current price feels expensive and heavy and we are all sure that as time goes by the price will increase further in the future. If you keep waiting too long, the chances are high. You can reduce your potential future profits and your potential ownership of the asset is much smaller.
