We saw a gap up today, reminds me of the good old days. :-)
We have broken out of above a months-old downtrend channel and above the 20-period EMA. We should wait for confirmation. With this sideways action, if you are clawing back in your portfolio, you can consider short-term profit taking or adding to your position when we re-test.
The biggest vulnerability at the moment is the overall stock market and how that will in the short term impact GBTC. It is fairly clear that any correction will result in short-term profit taking.
