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.
