The combination of 21 monthly EMA and the 61,8 fib level (that has stopped every previous rally) make me think that the price will make an other lower low. How ever I believe the bottom is close and I suggest you take some profits in the first level between 4450 and 4250. If price keep going up then I assume that bear market is over and the sun is shining again for BTC.
Next move is up for short-term as BTC will approach the diagonal resistance. Probably target will be at around 6900$ and Stop Loss at 6100$. Let's see how this descending triangle will behave afterwards.
