I made this little picture to sum up what happened in the last 24hours.
According to my opinion - ONLY - both stochastics gave a sell signal, followed by the EMA50 crossing down EMA200, which is a bearish indicator. Thats what caused the huge drop within 12hours. Now, the good news, the trendline barely managed to hold. RSI is still bullish and stochastics are about to give a new buy signal soon(TM).
As time goes buy i strongly believe this is a test for the week hands. Either whales or more experienced traders are testing the week hands in order to get a better discount on Bitcoin, cause they know that sooner or later it will start another rally.
Remember, were money is involved there is a lot of greed.
