For the past few months buying when price taps the 21 EMA has been consistently profitable (indicated by blue arrows). Ideally you would buy a 200 EMA tap (indicated by the green arrow). This is a simple way to not get caught in the Link fomo, as it is always dangerous to buy a parabolic move as we're seeing now. The red flag indicates when this trend ends as price falls below the both EMA's. Until then buying taps of these EMA's is a safe way to stack Link. I am personally waiting for price to return to these EMA's to make a long term investment in Link.
Blue Line - 200 EMA
Green - 89 EMA
