Wave 4 was a correction to the trendline and bounced nicely and was a typical "sell the news" after lots of hype for Segwit.
It seems to me that leg 5 has been started.
Broken out of downtrend, space for more upside. More good news coming and leg 5 may just be a zone for some natural correction.
SL below trendline for those who use SL in crypto ;-)
