Bitcoin is currently moving within a key support/resistance level.
It's very likely that 7800 $ is going to fail as a support, forcing Bitcoin towards the next key zone, which would be around 7150$-6900$ (0.786 Retracement + Trendline from March 2k17).
Stoch RSI indicates further downwards momentum.
If the afore mentioned support fails yet again, it's likely that Bitcoin is going to test 5.800$.
