In the old CDPs you could pay your accrued interest with MKR
Now I see option to pay back everything only in DAI and then withdraw all the eth and the CDP stays open, is that supposed to be so?
I remember the idea before was to pay the interst in MKR and that MKR was burned, hence MKR was good investment if makerdao is widely used.
Is the acrued interest in DAI used to buy MKR now and burn it or what is the dynamic now and why the changes?
