I came across this news yesterday, as I am always keeping an eye on this type of news.
One of the first a must to obey rules I got to learn when I arrived in the blockchain is to not keep any cryptos on the exchanges. It turns out that the biggest percentage of hackers attacks are namely against the exchanges.
People should know about that and be more mindful with their funds!
Thanks for sharing this info with us!
