You’re also forgetting the part of being hacked, because I can remember that the exchange was once hacked around 2020 (last year), although no funds were lost in that case. According to blockfi.com the hackerSIM-Swapped one of their employees phone, and that was what led to their platform being hacked.
So please tell me, what’s the possibility of such thing not repeating itself again? Unless they are going to be very careful this time, making sure that they avoid anything that would lead to such events happening again. Although I do know that this kind of events hardly occurs, because we hardly see news of big exchanges being hacked.
PancakeSwap is a non-custodial exchange or a "DEX" as they call it, hence there is no user "account" that can be sim-swapped as with custodial exchanges such as BlockFi; pretty similar to how the likes of the famous UniSwap/SushiSwap works.
