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 that is right bitcoin day will play important role in promoting bitcoin. i think it will be more helpful to introduce bitcoin in such area where people do not know about bitcoin.
Just (if) bitcoin day is fixed into specific day and will be held every year, but, if people don't really know what it is and don't even know that bitcoin day has existed, then, it's such a waste of effort. There are damn many days about something out there which I don't even know what it is just if google doesn't change their logos in their main page to celebrate those days I'll be probably never be informed of such things.
