prices than what they're selling them for elsewhere online. In addition, 7k Metals has a buyback price that is about 10% lower than what you pay for it. I imagine a lot of people will sign up and buy metal. They'll then get into a situation where they need liquid cash and sell back their metal to 7K and lose 10%.
I would imagine that 7K Metal's business model is to sell stuff at roughly market rates, then buy back at a 10% discount.
