See that disclaimer thing and it do simply says that you would need to store up that USDT untouched for a year.
Disclaimer: If the user will release funds from the savings account before the settlement period, the user will lose all interest earned during the uncompleted settlement period. (see Terms and conditions linked below).
Question, where does the platform do get that annual profit given into its hodlers yet we are talking stable coin on here.

Please check the platform and you will have an answer to your question. We are a crypto backed lending platform. That's why the main source of our profit is loans interest rates.
The disclaimer doesn't mean that you have to stay your funds untouched for the year because the settlement period is 1 month(not year). Does it reply to your questions?
