What are the dangers of storing cryptocurrencies?

Cryptocurrency exchanges and online wallets are not immune from cyber theft. The infamous example of the Mt Gox Bitcoin exchange highlights this. Historically, Mt Gox was the world's largest Bitcoin exchange until it filed for bankruptcy in 2014 after security was compromised. In February 2014, Mt Gox had 850,000 Bitcoins worth $450 million before the exchange was ravaged by hackers. It is believed that the private key of the Mt Gox digital wallet was stolen in 2011. You can avoid these risks when trading STEEM CFDs because no wallet is required.
