So we are in very bullish conditions and the market seems very stable compared to 2017.
Fib levels tells me that we hit 23-24k first before a small retracement to test ath at 20k before we it goes to our new ATH at 42-44k.
Bitcoin seems to extend the fib targets with about 1k before it retraces, last target were at 18600 but extended to 19k.
Any correction below 16.5 would make me a bit worried.
