1. About BB Middle Band
Last time (September 2014) when 1M candle closed under Middle Band the price dropped by 58% over few months. So this level is very important and you should observe it very carefully.
2. The lowest gap in BTC Futures reaches 6380$ and in my opinion we'll bounce from this level (possibly a little lower) and our next step will be lower border of 1D Ichimoku Cloud which is 7000$ level at this moment.
Sorry for my bad English ;)
