I'm surprised it never actually made it to $100, with people as excited and irrationally bullish as they have been of late. Now I'm not sure if it will ever see $100 this year at all (it may, but it's questionable). It's just been kinda flat/dead lately with unusually low volume, which was not quite what I expected this week but does make sense.
It's Easter now, which is a massive (western) worldwide holiday. A lot of people travel or spend a lot of time with their families during Easter, and banks are on holiday as well.
If you look at bitcoincharts (
http://www.bitcoincharts.com/charts/mtgoxUSD#rg5ztgOzm1g10zm2g25zv ) you'll see that the action starts to quiet down on Good Friday, when people get do their last moves before going for a holiday, and then basically dies for the weekend with lower volumes than during normal weekends. There is no cash flowing in due to banks being closed and people are 'offline' due to being on vacation. As the exhanges are online, I am a bit surprised the price hasn't gone down, since people do have the chance of selling while new money is not available.
On monday the action will likely pick up a little bit, but it's still a western holiday so it'll probably be much quieter than a normal monday. Come tuesday, the game is back on. Even as us geeks spend loads of time online 24/7 and here in bitcointalk it's fun to look at how the coin is doing, it doesn't mean the rest of the world has got nothing better to do during holidays.
The lower volumes can be explained by the holidays, not by us being close to $100.
