It seems that Syscoin cryotocurrency blockchain has been compromised. It reason behind this is that more than one billion of its coin were mined in a single block. This is peculiar because the sys coin total supply is 888 million less than the mined amount in a single block.
Sys coin community confirmed on Twitter account that its blockchain has been compromised, and stated that they asked all the exchanges to stop the trading .
On Binance Exchange one single Sys coin was bought at price of 96 btc.
The redicuously high buy order placed on binance led to sudden pump in sys coin price.
