A senior executive at financial services firm Guggenheim Partners — which is planning to seek investment exposure to Bitcoin (BTC) — has argued that BTC is poised to drop to $20,000.Scott Minerd, Guggenheim’s chief investment officer, believes that Bitcoin will not hit another all-time high in 2021, according to a Jan. 21 episode of CNBC's Closing Bell.After hitting $42,000 price level on Jan. 8, Bitcoin is unlikely to climb any higher until 2022, Minerd said: “I think for the time being, we probably put in the top for bitcoin for the next year or so. And we're likely to see a full retracement back toward the 20,000 level.”
