Bitcoin is quickly beginning to attract the attention of regulators in a number of countries. After a flat-out ban in Thailand and restrictions on banks in China, now several Indian Bitcoin exchanges have suspended operations following a warning from the Reserve Bank of India concerning digital currencies. Issued December 24th, the statement outlines the risks of a purely electronic wallet, unregulated transactions and value fluctuations. It also contains what could be considered a threat, however, stating that virtual currency users could be breaking money laundering and terrorism financing laws -- one report from the subcontinent suggests the government has carried out the first raid on a Bitcoin exchange, too. Thus, some sites have decided to close for the time-being, leaving notes on their homepages expressing the need for clear legal guidelines before trading can resume. Undoubtedly we'll see more countries take steps towards regulation, especially as the price of currencies rise. Nothing decreases something's worth like outlawing it, after all.
