Will Bitcoin (BTC-USD) and other cryptocurrencies recover from their steep slump? That's a question digital asset traders are facing, and Bitcoin's decline has brought down crypto-centered assets like Marathon Digital Holdings (NASDAQ: MARA) stock. Yet, I'm bullish on Marathon Digital Holdings stock as a turn in the crypto tide could precipitate a swift comeback. Based in Las Vegas, Marathon Digital Holdings is primarily known as a Bitcoin miner. As we'll discover, Marathon isn't a profitable business, and it's understandable if this is a deal-breaker for some traders. On the other hand, Marathon has a vast cryptocurrency mining fleet and is quickly ramping up its Bitcoin mining pace.
