Besides Digix Gold tokens on the ETH blockchain, what other gold-backed tokens are legitimate on the crypto/Blockchain space? I've stumbled across many in the past, only to be a complete scam. Regulation is necessary here in order to provide investors with legitimate tokens that are backed by Gold powered by Blockchain technology. If renowned companies start offering Gold services on the Blockchain, it would've been truly revolutionary.
I'd like to know of other options to invest in Gold without actually owning it. Redeeming virtual Gold tokens to cash or physical bullion all using Blockchain tech, could prove to be extremely convenient for long term investors. Imagine being able to sell your Gold-backed token to physical Gold right from the Blockchain without middleman. It'll truly revolutionize the Gold industry. The middleman will only be responsible for shipping out the physical bullion, but transactions will be settled on-chain.

If you happen to know of any other gold-backed tokens besides Digix that are legitimate, please feel free to share it with me here. Any help, suggestions, or recommendations will be greatly appreciated. Thanks in advance.
