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 %
Withdrawal Fee: 0.01 BOC

0x is a decentralized exchange built on the Ethereum blockchain that allows for ERC20 tokens to be traded. 0x hopes to serve as a building block for creating decentralized exchanges.
It is an open-source system of smart contracts that acts as a platform for those wanting to build with the 0x protocol. Augur, Aragon and several other projects are using 0x, at the moment.
The 0x protocol addresses some of the common issues that plague other decentralized exchanges. 0x is faster, more liquid, and less expensive to run. Its speed is due to reduced blockchain congestion. This is achieved by moving all transactions off of the blockchain and then verifying them. This move, also allows for the elimination of transaction fees by reducing the reliance on the blockchain. 0x doesn’t charge fees of any type to use the protocol. However, Relayers that create their own decentralized exchange can charge fees.
The 0x Project uses the 0x Ethereum token, known as ZRX, that allows users to pay Relayers’ transaction fees. It is also a decentralized form of governance for the 0x protocol system. Anyone holding ZRX can give input about improving the protocol.
