South Korea is preparing to tax bitcoin use after the cryptocurrencys trading volume skyrocketed past that of Kosdaq.
Death and taxes ... it seems that even bitcoins can't escape that

If you think the idea behind Bitcoin is to avoid paying taxes, then you are wrong. You should always pay the taxes that are
due, because it is the law. If you use Bitcoin for tax evasion, you will be caught and you will face stiff penalties and/or some
jail time. Bitcoin is just a currency or some might say a speculative commodity.
