Before I even looked at this chart, I knew that Bitcoin had risen because ETHUSD was trading at around ~$11 (Now ~$12). To me it looks that people are selling their Ethereum for Bitcoin, and when bitcoin pulls back people are selling their Bitcoin for Ethereum. It would not surprise me if we saw a nice spike in ETHUSD if Bitcoin pulls back from this rise.
From the Linear regression line, it seems to me that it is too early for Bitcoin to be able to break the 38.2% resistance line. I like to believe that this rise is in part being created by speculation over the upcoming halving. Considering the ETA is 7-10, it is not surprising that Bitcoin looks ready to test the 38.2% resistance line by ~7-24. If the trend continues to keep pace, we should see the slope of the trend line increase which would suggest a possible breakout attempt before the halving.
My Recommendation: If you are sitting on a profitable position right now, consider allocating some money to ETHUSD. You will benefit handsomely if Bitcoin does a pullback.
