Dash has seen a tremendous downward trend from 0.1+ BTC to now roughly 0.035 BTC/DASH.
Now the previous resistance of the rally in march 2017 is again tested as support level like in Nov&Dec 2017 where it held very well.
I would give this trade a high probability to the upside (also considering Crypto markets seem to turn slightly more bullish again), however if the support level fails I expect a full retrace and would place a stop at around 0.03-0.031 BTC
