Binance Trading Suspension: SYS Trading IrregularitiesDuring its maintenance, the Binance internal risk management system found irregular traders in a number of API users. This prompted the suspension of trading and withdrawals on the Binance platform. The suspension of withdrawals and trades was not originally planned but was a decision made during the maintenance process. Syscoin, a fork of the Bitcoin protocol, announced yesterday that it had noticed a potential issue and asked major exchanges to suspend the trading of SYS immediately.
This is what prompted Binance's maintenance, and when irregularities were found, action was taken. Binance responded to its users affected by the SYS price fluctuation and said: "For the users who were negatively affected by choosing to trade the rising SYS price, Binance will offer zero-fee trading between 2018/07/05 - 2018/07/14. If you traded SYS during the incident and believe you were negatively affected, please open a support ticket." In addition to this, all other Binance users will be given a 70% rebate of the trading fees received from Binance (not including referrals) between July 5th and July 14th. This rebate will be paid out in BNB and calculated using the closing price on the 14th. >> Binance Halts Trade in System Upgrade
We are investigating a possible issue on the Syscoin blockchain, nothing is confirmed but we have asked for exchanges to halt trading while we investigate.— Syscoin (@syscoin) July 3, 2018
