Pros & cons of using Coffee grinds?

I have been saving up coffee grinds to add to a compost bin for top dressing blueberries but I have recently read somewhere online that coffee grinds still retain traces of caffeine that suppresses growth in plants. The plants in the wild use this as a defence mechanism to stop other plants encroaching on their patch. Anyone else read this & should I be wary of using Coffee grinds in my compost?
I would ‘t worry too much about it. The rotting action in the heap will probably destroy the caffeine anyway.
If you live in Derbyshire, as I do.
A few weeks back I noticed the leaves of one of my strawberry plants were going yellow and it was massively behind the other in terms of growth....flowers had stopped opening and this not been pollinated...I added coffee grounds for a "hit" of nitrogen and they did the trick quite nicely! I've sence put in some manure and they're now lushously green again, but the coffee definitely did the trick and itsnow almost caught up in terms of overall plant size.
