onboard directly from Goldmoney
Goldmoney sucks, their card doesn't work, you can't take crypto out of it (only send it there to buy gold at awful rates) but you can have your gold shipped to you. It would be really, really cool if I could request a physical gold withdraw form Goldmoney and ship it straight to Vaultoro's vault. And then have the Vaultoro trading system instead (which is a proper exchange, rather than that concierge weirdo they've built at goldmoney).
Maybe I'm trying to solve my gold liquidity issues, but this could be a great way to growthhack your way by getting customers from Goldmoney and providing them with better service.
