What happened Many stocks with a financial interest in leading cryptocurrency Bitcoin (CRYPTO: BTC) traded sharply higher on Monday morning. A cautiously bullish Bitcoin report from well-respected analyst firm Citi sparked the jump, assisted by a modest rebound in cryptocurrency prices after a difficult end to February. Here are some of the morning's leading Bitcoin gainers, including a few household names that are not always seen as cryptocurrency investments: Company Cryptocurrency Business Max Gain on March 1, 2021 The9 (NASDAQ: NCTY) China-based Bitcoin miner 43.1% Marathon Patent Group (NASDAQ: MARA) Cryptocurrency miner, digital asset manager 22% Riot Blockchain (NASDAQ: RIOT) Colorado-based Bitcoin miner 19.2% Paypal Holdings (NASDAQ: PYPL) Enables U.S. customers to buy and sell four cryptocurrencies, including Bitcoin 5.5% Square (NYSE: SQ) Enables Bitcoin transactions through Cash App, invested $220 million in Bitcoin 4.8% Data source: Yahoo! Finance, noon EST, March 1, 2021. So what In a note sent to Citi's investment clients on Monday morning, managing director Kathleen Boyle said that Bitcoin stands at a "tipping point" right now. Citing high interest in Bitcoin futures and Bitcoin's potential role as a long-term inflation hedge for large investors, Boyle argued that the cryptocurrency "balances at the tipping point of mainstream acceptance or a speculative implosion." The analyst provided incisive analysis of both the bull and bear cases for Bitcoin, but the mere existence of a balanced report from one of the world's largest banks should be counted as a positive development. Megabanks like Citi and JPMorgan are starting to take Bitcoin seriously, and that's a big shift from the largely dismissive views they have held in the past. It's no surprise to see Bitcoin investors focusing on the bullish parts of Boyle's analysis. At press time, Bitcoin shares traded 12% higher in 24 hours amid a generally positive cryptocurrency market. Image source: Getty Images. Now what The mainstream names are arguably the bigger story. The big jumps in The9, Marathon, and Riot Blockchain added a total of $1.1 billion to the total market value of these stocks. Square's small move boosted that stock's market cap by $4.4 billion, and digital finance giant PayPal added $14.8 billion to its massive footprint. Cryptocurrency mining is still a risky and often unprofitable business, while Square and PayPal are attempting to use cryptocurrencies like Bitcoin as a medium for sending, receiving, and saving money. Bitcoin remains a rather volatile and risky investment vehicle, but the level of risk is reduced every time a major voice in the traditional money management world lends its support to the digital currency. That's what happened today, moving Bitcoin and other cryptocurrencies one small step closer to long-term stability for value-minded investors.
