Price fluctuations are quite normal. We must not forget that the BTC has had an incredible rally in the last few days and weeks.
There are currently many large investors in the market, which sometimes take profits, and then re-enter at lower prices. That's exactly what we saw in the last few hours, when the Kurzs moved in a rage of $ 1000.
The long-term uptrend is in tact. If no unusual bad news come the journey continues.
It's only in the very short term that people can look at the price movement and get nervous, in any longer term chart the uptrend is amazing. I think people are just so used to assets that fluctuate a few percentage points a month or a year, that when one comes along that can and does fluctuate that much in a few minutes and even more in a few hours, it's very tough for them to keep those swings in perspective. Some say it's best for long term investors in any asset to ignore the very short term moves, which of course is impossible with Bitcoin because it's just so damn fun to watch the rollercoaster, especially if it's swinging up.
