I will not take your important time to make you understand what's MOAT.
Just read a short story
Suppose I have a juice shop which runs during summer.
AROUND my shop there are many other juice shop because it's low capital intensive and anyone can set up.
Now you ask why am I selling 20 per glass while my competitor @18 per glass.
Why people are paying additional 2 per glass
And there is a large tree where my juice shop situated and the tree ownership belongs to me because it's before my house.
This tree is too big and provides natural air and shade to people who come to drink juice during summer.
Thats why they are charging 18 per glass while I am charging 20/glass.
Thats why they are operating at less margins while I am operating at high margin.
