If you think that everything using a blockchain is decentralized, you are incurring a big mistake. While in bitcoin there is no way to recover funds if you make wrong transactions and obviously there is no backend assistance service(!) this is not the case in altcoins where there are always organizations and companies behind. This is a good reason to stay away. As they can assist and “recover”, they can also interfer with a transaction and with your funds, exactly as a traditional bank does with fiat money.
Tether (USDT) is the largest stablecoin (ie crypto asset pegged to the value the US dollar, believing that this means “stable”) in the world. It is the largest stable coin and also a big market capitalization cryptocurrency. It is used mainly by traders in cryptocurrencies.
Here an example very clear with a tweet from a guy of support(null)
So if you think that this kind of “assistance” is useful and welcomed, you are not thinking decentralized and you are not thinking to cryptocurrencies as a way to get rid of bank dominance and control. Only bitcoin is able today to guarantee independence and freedom from central banks, governments and other political powers.
