Kenseilon writes "The Verge reports that millions of Dogecoins — an alternative cryptocurrency — was stolen after the service DogeWallet was hacked. DogeWallet worked like a bank account for the currency, and the attackers modified it to make sure all transactions ended up in a wallet of their choice. This latest incident is just one in the long (and growing) list of problems that cryptocurrencies are currently facing. It brings to mind the incident where bitcoin exchange service GBL vanished and took a modest amount of Bitcoins with them. While not a similar case, it highlights the difficulties with trusting service provides in this market."
