On daily chart, BTC broke a huge trendline and the price is retesting it, if the retest is succesfull we could see BTC continuing upward momentum. It could always be a bulltrap and we have to be carefull at this time. Volume at highest price is still low and that is a good sign but we can´t rely only on that. Only time will tell. Fear and Greed index is showing that market is being greedy and that is a sign of a possible pullback.
However on 1H chart we can see Bitcoin broke down a local key level (51K approx), we could expect a retest of this level and a continuation torwards next local support around 47K. If that is the case I will be looking at buying altcoins after watching how Bitcoin reacts to the support as we could be seeing nice pullback on alts.
