There are approx. 300 merchants on Coinpayments, which means you could earn up to 150,000 MUE.
Which is worth currently around $20,000.00+
As you can see from here we have only 7 merchants accepting MUE on the coinpayments directory

This is because since we migrated from quark to the new X11 wallet, many of the "old" merchants who accepted MUE didn't migrate over with us.
Here is the old list (38 merchants)

- Proof the store has been added
- Proof of your contact with the store
- Your MUE wallet address
