Cryptocurrencies were supposed to offer a secure, digital way to conduct financial transactions, but they have been dogged by doubts. Concerns have largely focused on their astronomical gains in value and the likelihood of painful price crashes. Equally perilous, though, are the exchanges where virtual currencies are bought, sold and stored. These exchanges, which match buyers and sellers and sometimes hold traders’ funds, have become magnets for fraud and mires of technological dysfunction, a Reuters examination shows, posing an underappreciated risk to anyone who trades digital coins.
A major Bitcoin exchange, Bitfinex, was hacked and nearly 120,000 BTC (around $60m) was stolen. The price of Bitcoin promptly crashed, and Bitfinex was forced to suspend trading. Suddenly, Ethereum was not the only basket case cryptocurrency around.
Its collapse into bankruptcy last week – and the disappearance of $460 million, apparently stolen by hackers, and another $27.4 million missing from its bank accounts – came as little surprise to people who had knowledge of the Tokyo-based company's inner workings.
