Currently i see another signal this time it involves the lines and assuming we will retrace once again as much as we did back in 2015.
This signal it's known as the death cross when the 50 line crosses below the 100 line (Green and red lines)
Back in October 2015 the 50 line cross up the 100 and it went on to perform an almost 3 year bull-trend finishing on 20,000$. Now it seems we are entering a long term bear trend, in the past when bitcoin -3.10% entered a bear market it dropped around 85%-89% from the top. If the market is set out to do this once again this will mark the bottom around 2500$-3000$ from current top which also aligns with the long term uptrend created since October 2015, (of course there are possibilities some exchanges create some wicks below 2000$ due to massive panic in the market giving some people great buys)
This is a long term outlook and it could take months or even years to happen.
