Did Rubidium Hat make money for release buyers?
Rubidium Hat sold out of its original stock on its first day of sales, Nov 19, 2023. Copies could be resold from Dec 19, 2023, once Roblox's 30-day resale lock ended.
For someone who bought at the original 125 Robux, the best return per day held came from reselling about 30 days after release, when copies were selling for around 399 Robux. That works out to roughly 75 Robux profit per copy after Roblox's cut.
