I disagree with the $8K mark as the indication that we are going bullish. Its really hard to say which price. We have a lot of arguments month back that bitcoin won't go below $10K and we did and we are struggling to get to 4 digits again. So the big mental barrier is the 4 digit mark, if we surpassed it and then like become stable and sustainable then most probably we can see the the trend shifting from  bearish to bullish sentiments.
