13k can barely get $25. On ROBLOX, most people who buy and sell their ROBUX on the black market go by this: $1 = R$1,000. The prices to buy ROBUX don't mean anything to buyers in the black market. (I'm an experienced LMaD'er with 26,000 posts on ROBLOX so I know).
Also:
I have already cashed out 100k in April, am gonna wait a bit and try to make a little more if I can.
