San Francisco’s transport agency has been hit by a hack attack that led to customers being able to travel for nothing. The hackers have made a ransom demand of 100 Bitcoin, which amounts to about $70,000 (£56,000 ; €66,000).  As a precaution, staff shut off all ticketing machines on the network.

2) Is Bitcoin, a digitally untraceable currency, a good idea?
