In my research it shows that adding the coffee grounds directly from your use to the worm bin poses no issues.
On average a daily amount of 6-9 Tablespoons is added to the bins with no issues.
When you are separately composting the coffee in another bucket you are just doing some of the worms work for them! That is perfectly fine, if that works for you.
