Change nick name for gold. :beer: :wallbash

Hi, last month i play the game in my house, i have a problem with my nickname. I was with a friend and I started drinking wine.

entered the profile and accidentally clicked on the nickname and then entered, now I can't change the nickname.I propose that to solve this, the name can be changed using a sum of gold.I know, I was drunk and it was my mistake, but I wish I could personalize my name.
