I get that.
So basically, it is not a high or low fees thing and just an angle/ a way of looking at it as when you send a low fee transaction and unfortunately network clogs down, you will wait while higher fee payers will enjoy their transactions being confirmed earlier than yours and if the fee drops immediately after some transactions and you just wait till that time for that fee drop to come, then I think there is no need to send a transaction when fees are high.
And what happens if the prediction fails due to a mempool clog?
I will not bother to see it for 24 hours too but will you take it for 2 days after trusting the wallet's fee prediction? We have seen that happening in the past days already.
