Update:
We've now officially broken down through my purple support line on the 4h chart - on the daily chart we're still good, so there are still 12h left to make this break become just a wick on the daily. A Death Cross has formed on the 4h chart which concerns me a little, but can be fixed with a strong bounce upwards. RSI is oversold on the 1h chart.
Around 4050 satoshis is the key level to watch, since there is the support of the .382 fib level as well as the 50-day SMA. As long as this holds, I'm bullish.
