While bitcoin (BTC-USD) retreats a hair from its record high of $64.9K, a number of bitcoin-linked names are sliding a bit more than that.MicroStrategy ([[MSTR]] -8.8%), Marathon Digital ([[MARA]] -10.2%), and Riot Blockchain ([[RIOT]] -8.5%) stocks take a breather as investors watch for the first trade of Coinbase Global (COIN) on the Nasdaq.Fintechs Square ([[SQ]] -3.8%) and PayPal ([[PYPL]] -1.7%), which both have bitcoin-related business segments, also drop.With bitcoin recently traded at $63.1K, Goldman Sachs CEO David Solomon, appearing on CNBC, says the cryptocurrency is "on an inevitable path to have the same market capitalization and then a higher one than gold."It's all a question of how quickly the adoption of bitcoin will occur, and in Solomon's view it's "happening faster than I had predicted."See the recent decline in MARA, MSTR, and RIOT stocks in the five-day chart below.Compare key stats of RIOT, MARA, MSTR and SQ via Seeking Alpha's
