Firstly, I want to say that the long-term coincides with the 1x8 angle and it holds and this is a good sign.
Secondly, I see signs of the beginning of a new cycle.
I've already seen a similar chart somewhere and this is a BTC chart before he started parabolic growth.
Congrats to all in NEM/XEM, I think that you made a very successful long-term investment!
As for the scenario, yes indeed such a probability exists.
Look at the chart, where you see the support below? ~10 cents, right?
What should happen with the top10 cryptocurrency to lost about half of the capitalization?
Of course in the cryptoworld anything can happen, but I personally think that such a probability is not high.
Trade at your own risk.
