Bitcoin is currently very overbought at every chart. As you can see we just formed a flag and are currently waiting for the e-wave. 4000$ are very possible. This can also happen very fast like after reaching the ATH .
At this time we had 5 days until reaching $11000 from $20000.
$12000 a heavy resistance zone (shooting star).
Indicators are also showing bearish signals.
We need to break $10800-10400 to continue the waterfall.
