What do you do with Sythe Gold?

[Vanilla RS]

I've been collecting Sythe gold since I've created my account, I've been wondering what I could do with them.

Is there a store or something that I could buy or trade things with people?

Or is it just something that you just have.

 

Basically, something you just have, use to be able buy early bumps with it, but people were abusing it

 

Some people like to collect it.
You can buy and sell it here.
