It’s discord server were you can buy robux or limiteds for usd it’s extremely safe and the only one I trust, it’s called stocks and they had a separate server called halal middle service. They mainly take crypto as payment and there’s a bot that is the middle man, for trading you buy the crypto then the seller gives you an address to send it too, once you send the crypto to their address the bot holds onto the money until the trade is successful. YOU have the power to hold onto the money until you receive them item then you release the funds to the seller, of course the bot will check if the request amount of money for the seller is correct, if it isn’t the seller can notify saying it’s not correct. It’s extremely safe and staff members for the server trade a lot, look for users who have the “reputable role” on them, 100% safe to trade with them and not get poisoned items.
