DigixDAO reached the hard cap of $5,5 million within 12 hours of ICO, while the hard cap of GoldMint was higher ($7.3 million), and they didn't manage to collect it.
GoldMint: MNT is traded, GOLD is an internal currency and is the proof of owning physical gold. The ticker for tokens sold during ICO was MNTP, which later migrated to MNT (GoldMint Blockchain). These tokens are needed to verify transactions in GOLD. The more MNT tokens users have, the more transactions they can verify.
