People usually save taxes while having their wealth in tether, don't know why they will keep their money in government issued stable coins.
If the choices are only between the two then why not? It's probably more secure to use the digital fiat issued by Governments than let a privately owned company control your wealth. Let's not forget that USDT is not really decentralized and can still be frozen by Tether at anytime even if it's stored in you non-custodial wallet.
I am talking in terms of taxes. If you put all your stable coins in government issued CBDC, government can easily know if you are paying tax on them or not. Many people haven't declared their crypto assets to the government and when suddenly they transfer their wealth in CBDC, it will raise questions as to where this wealth came from and why it was kept hidden for all those years.
Yes, moving forward if you have fiat money and you want to convert it into digital currency, it is far better to use CBDC than the tether. Also, when every country has their own CBDC, the role of paper money will be limited.
