I will send money to AAAFX in the next months. A forex broker. They accept USDT transfer or Credit card deposits from my country. Credit card will be costly due to currency conversion and other fees.
How can I send USDT to that firm? No longer I am working with crypto's. Too old for that.
I have a fear that I can make a mistake and it is nonrefundable in cryptos if anything goes wrong.
If you don't want to use cryptocurrency, USDT for your payment because you are fearful of making mistake and losing your money, you can use Credit card which is a familiar payment method with you.
You can learn to do it with USDT which is a stable coin and is deployed on many blockchains. When you make your USDT transactions, make sure you choose a similar blockchain, sometimes with MEMO tag for some blockchains, for both where you send your USDT to and where you receive your USDT like on AAAFX.
I do not want to open a wallet - I did that 12 years ago.
I don't know that 12 years ago, USDT was available in Bitcoin market. [1] It was launched in 2014, 10 years ago.
