Who it suits
A first run. Seven days at a minimal amount shows you the whole mechanism (deposit, accrual, claim, principal back) for the price of a coffee and one week of patience. As a way to learn how it behaves, it beats reading about it. At 100 USDT the seven days return 3 USDT, which is the whole lesson: you watch daily accrual appear, a claim settle and the deposit come back, and you have your answer inside a fortnight.
