If this leg materializes on the upside it will most likely be the last one of this bull trend, establishing a range for future reference and price discovery. let's see what happens, potential, or better hype is huge. on the downside we have a more longterm safe retest of a normalized trendline , which i never used but sometimes are useful to explain how vertical a trend is getting.
Technicals aside, we are always on the edge of total collapse with bitcoin , this time with BU hardfork :)
