When Mt. Gox collapsed in 2014, some 650,000 bitcoins were lost. While it was a rather big sum four years ago, it is now worth $5.2 billion. Another big failure may result in a total loss of confidence in the cryptocurrency, resulting in an exodus to fiat money and commodities.
Last week, $500 million in NEM cryptocurrency were stolen, adding more concerns about the lack of security of investing in cryptocurrencies.
