Greeks flock to Bitcoin

Bitcoin exchanges are reporting a surge in interest from Greek users faced with shuttered banks and capital controls.

Ahead of a referendum on creditor proposals for Greek reforms in return for vital bailout funds, this week the country’s banks are shut and a EUR60 daily withdrawal limit has been imposed.

The move appears to have prompted many to turn to cryptocurrencies. Bitstamp says that trades from Greece are currently up 79% on their 10 week average, while German and Chinese-based exchanges are also reporting a surge in users from the troubled country.

Whether Bitcoin is of much immediate use to cash-starved Greeks is debatable: according to CNN Athens is home to just half a dozen merchants - including a yacht rental outfit - that accept it.

Meanwhile, the crisis appears to be having an effect on Bitcoin’s price, with the currency’s value rising from around $245 a week ago to $265. Some are betting on a far bigger surge if Greece leaves the Euro, with Bitpay co-founder Tony Gallippi predicting that the $1000 barrier could be broken.
