From the Blue Line PRO Service on October 27th: "GBTC (Grayscale Bitcoin Trust) has generated a short-term Buy Signal, one that could easily morph into an intermediate term signal with continued strength." That continued strength has carried GBTC to $18.75 this morning, enough to confirm an Intermediate Term trend. Note on the chart below shows how the $17.50 level was broken last week and prices are continuing to rise well above it. Stop on a close below $15. We will be raising this once GBTC reaches into the 20's.
