There should have been some sort of way out with mixer. For example, getting collective coins in a batch and lowering the fees for sender.
Won't this compromise privacy? You know, the major reason we always opt for a mixer is privacy.
Also, I don't think batch transaction will lower the fees dramatically.
Imagine a jump in the normal transaction fee rate from let's 3 sats/vbyte a few weeks to 300 sats/vbyte today... That's a 9,900% increase in fees
Anyways this is way temporary issue it seems.
Temporary, if the Devs and bitcoin community do something about it.
