If we look at the day chart, we can see, that the price broke the resistance level, which was on 1.8 (the line of falling tops of a downtrend). After that, there was a small expected pullback, after which, I think, there will again be a test of the resistance line. If the price breaks through it again, a significant increase is expected. 1.66 - 1.73 can be considered as a good entry spot.
