Your profile picture is a key element of your profile. As you send and receive payments from your contacts, it is essential that you get recognised in a second and that your profile picture is YOU and is authentic.
Here are a couple of rules to apply when you add a profile picture:
Pick a photo that looks like you
Use a high-resolution image
Make sure your face takes up at least 60% of the frame
Be the only person in the picture
Get someone else to take the picture for you
Avoid distracting backgrounds
