CryptoBridge is a decentralized exchange (DEX) powered by the BridgeCoin (BOC). BOC holders receive 50% of the profits that CryptoBridge collects from trading fees and become innvestors in the BridgeCoin exchange. In order to receive their share of the profits, users must stake part of their BOC holdings for a period of 1, 3, 6 or 12 months. The longer you stake your coins, the higher the staking bonus will be.
CryptoBridge is built on the Bitshares blockchain, which has relatively fast confirmation times.

Trading Fee: 0.2 %
