Bitcoin, the world’s most prominent cryptocurrency, has particularly been on a dream run over the past couple of months and the rally is set to gain pace in the coming months as multiple positive developments have given investors’ sentiment a boost.Bitcoin rallied past $43,000 in December 2023, and on Jan 2, it surged past the $45,000 mark for the first time since April 2022. Although the cryptocurrency retreated from its 21-month high, it hovered around $44,200 on Jan 4.Over the past three months, Bitcoin has rallied more than 61%. The Federal Reserve didn’t hike interest rates in its last three FOMC meetings in 2023 after raising interest rates by 525 basis points, as its aggressive monetary tightening campaign has seen inflation decline sharply.Cooling inflation has also raised hopes that the Federal Reserve will soon end its monetary tightening campaign and start cutting rates this year, which could be as early as in March. Higher interest rates have adverse effects on growth-focused sectors like technology, consumer discretionary and cryptocurrencies.Also, investors are optimistic about the imminent approval of a Bitcoin exchange-traded fund (ETF) by the Securities and Exchange Commission (SEC). This approval is expected to have a significant positive impact, providing strong support to the cryptocurrency market.Investors are currently looking forward to the potential approval of a spot Bitcoin ETF by the SEC as early as the first half of 2024. Stocks to WatchCoinbase Global, Inc. (COIN) offers financial infrastructure and technology to support the global cryptocurrency economy.
