This is surely a bad thing to happen to bitcoins. Bitcoin's one advantage is that it is not affected by local taxes. This makes transactions cheaper than local transactions in banks. Bitcoin is so volatile and it can be transferred easily because it does not undergo any processes which banks and governments have. If this will happen and if many countries will be able to implement this surely bitcoin's price will go down gradually. I hope this won't get any further so bitcoin will remain and will constantly grow.
