What to do with gold/coins after you're BiS

Basically title. I got my main fully BiS and got no interest gearing or making any alt. Any advice what to do with gold and/or coins?

Ty!

You can use gold for gold sink mounts and achievements. Like Traveller's Tundra Mammuth, Chopper, Cenarion Expedition mount. Also you could start Insane rep farm. That will require quite a lot of gold to make things easier.

Give it to the poor

. .

Sell them for coins.

I usually start saving gold and consumables as a collection and unleash my impulse buying at that point.

Keep some gold for random expenses (mount, crafted items or raiding related stuff) and sell the rest for coins. Once you have use for those coins, spend them.
