After challenging its all-time high in November, Bitcoin sold off and has now traded in a range between $35,000 and $47,000.For those used to triple-digit percentage moves in BTC, this is peace and quiet.While Bitcoin consolidates, we should look ahead to some catalysts that might break it out of its range.The most important of these catalysts in my opinion is the Grayscale GBTC ETF conversion, which could allow retail investors to finally have a low-cost, liquid and safe way to invest in BTC on public stock exchanges.
