Cryptocurrency investors have experienced a real rollercoaster in the last few years — the likes of Bitcoin, Ethereum and Ripple have had incredible highs and crashes, and investors have seen big gains and losses in tandem.
Despite that volatility, many market participants are still interested in how to enter and make money in the cryptocurrency sector. But depending on how you look at it, perhaps the bigger story is blockchain technology, the backbone of crypto.
A blockchain is a digitized and decentralized public ledger that has many applications in different industries as a way to provide transparency. In the crypto realm, blockchain is used to record all cryptocurrency transactions, and it is also the mechanism through which some digital currencies like Bitcoin are “mined” into existence.
The technology has become a popular investment in its own right for savvy investors. Not only are there many blockchain-focused tech stocks, large companies like Meta Platforms (NASDAQ:META), IBM (NYSE:IBM) and Microsoft (NASDAQ:MSFT) have invested in blockchain technology. These corporations see the potential for blockchain to play a role in sectors such as driverless vehicles, food safety and fintech.
For those new to the blockchain space, deciding on a specific company to invest in may seem overwhelming, especially with the current market uncertainty around cryptocurrency price movements.
That’s where exchange-traded funds (ETFs) come in. What are blockchain ETFs? In simple terms, ETFs are marketable securities that track an index, a commodity, bonds or a basket of assets like an index fund. ETFs trade like a stock on an exchange, and each ETF owns its underlying assets, dividing them up into shares that are available to investors.
