In Theories is yes but in reality we do know since
APY in most of the Dentralalized Finance is fluctuated meaning it keep changing not a fixed rate so it would be risky if you take a lon and the APY is change ~
The answers you provide are surely the reason why I raise such questions. It is technically improbable to sustain within the long term. By the time such a rate holds on for some time, it will attract another user to join the pool, in consequent the algorithm that set the economic system will kick in. In the end, the rate simply reduced.
Combined the fund came from the loaned fund, it will definitely increase the risk.
