Bitcoin mania alarms S. Korea

South Koreans are swept up in bitcoin mania and Seoul officials are scrambling to rein in the craze as regulators around the world warn of a bubble.

One group of traders in particular has set off alarm bells: students, drawn in by bitcoin's explosive surge this year.

On Wednesday (December 13), the government held an emergency meeting to try and find a solution.

It's weighing a ban on minors opening accounts on cryptocurrency exchanges and a tax on capital gains from trading virtual coins.

For now anyone with a phone and bank account can sign up to trade on South Korea's Bithumb, the world's busiest exchange.
