If you want to buy for the long-term, don't worry about these fluctuations - just buy your BTC and walk away for a year or two. Long term, BTC is either going to >$100, or <$1. Is it really gonna matter that much if you bought your first 20BTC at $12 or $14?

If you're just a short-term speculator or trend-trader, well, I'd hope you'd be a bit more sophisticated with your technical analysis/chart skills, and wouldn't need to consult the newbies forum...
