there was no bull run, that was a good increase not even a pump, it was very solid and slow a bull run is soem shit like the last ath rally
another reason why the 600 mark is a solid floor, is illustrated by the fact that even after the 120k bitcoin hacked, the price is still strong in that point
actually, i am quite surprised the price is holding pretty strong after something horrible happened. i would completely understand it if the price would be hovering around very low $500 prices right now, but it doesn't. maybe that's a sign that traders and the market are more and more maturing.
