Loopring is a decentralized exchange protocol and a “automatized carry-out system” that is built on Ethereum, with which users can trade with their assets on several exchanges. Right now, it is one of the ways Publish0x can earn you money, since you can tip LRC since a couple of weeks now.
The price of Loopring has risen very explosively in 2017, like most coins, but right now it trades at around 3 euro cent. The all time high was €2,41 (on 9-1-2017).

It’s important to explain that Loopring itself isn’t a decentralized exchange. It facilitates the decentralized exchange of assettrade by ring-sharing and order tuning. All orders are being filled simultaneously. This is the main benefit: efficiency, efficiency and efficiency.
The system of Loopring combines all orders by using the registered order of all the different exchanges so that all the prices can stay low. Furthermore, it gives users access to a bigger market, which in almost all cases lowers the prices.
