A BitCoin day is interesting. We should have one as it's going to be a big day in the future as it's probably one of the greatest inventions ever. If there is an internet day, then there should be a BitCoin day.
yes it is really interested, and i think bitcoin day will be too much helpful in promoting bitcoin. i think through this way people will know about bitcoin and hope that they will start taking interest in bitcoin and so bitcoin will become more and more trusted and reliable.
