Your comments are contradictory and untrue. Just like fiat in a bank, you don't have control over stablecoin because it is highly centralized. Don't deceive people into thinking stablecoins are safe because they are issued and controlled by third parties. Bitcoin stored in a non-custodian wallet is an example of a safe asset.
USDT and USDC are even worse to buy and hold because they are something else; they could easily be depegged under any circumstance if the issuance company has the possibility of its value returning to zero, and then again, instead of holding USDT, I will better advise the person to hold a physical USD and save it up on their personal volt; it's safer since there are no differences since it's still the same fiat.
So far, what I know about USDT is that it is a digital currency that has full support from the US dollar, so its liquidity value is higher, but the risks it carries are also very large. Moreover, the price movements of USDT and USDC are very slow and are not suitable for investment because it will be difficult to make a profit.
True wealth will make you to stay long in your wealth, by having different businesses around your country because they will start generating profits that will continue to accumulating your wealth in the country. But, fake wealth don't use to last long because if you verify the source of the wealth, you will know that it will not going to last long like those that invested in different businesses, and it will be very hard for such category of business owners to fall down to zero level in wealth because they are not depending on government in the country.
You want to acquire real wealth that will make you popular, I will advise you start investing in estate business and BTC business because there are many opportunity in those businesses that will make you wealthy which is the desire of many investors these days.
I'd say investing in real estate is more risky today than investing in Bitcoin. The chances are that the land you are buying today will turn out to be a fake wealth in the near future because of some poisonous plant was built near it or just because of the lack of infrastructure in the vicinity.
Each investment location will of course provide a different level of risk depending on the investment system offered. So there is no investment place that is free from risk. Therefore, we must wisely use the money we have by looking for information on the investment place you want to choose. In this way we can make decisions about where we want to invest with the money we have.
