For those thinking, "now's a great time to join the party!", the price surge happened from about March to about May of this year, with BTC more than doubling in USD price. However, it's been completely flat for over a month now -- longer than any other point in recent history -- and there are currently some big questions about the future of BTC that are being addressed next month and may result in a loss of value for some number of people, depending on how things shake out.

Smart money right now isn't in BTC, unless you think you can predict what's going to happen in the next six months and you're willing to keep it for a longer period. And, even then, you'd be better off selling it back to USD and re-buying when it likely falls back down to sub-$2000 in a month.
