Blockchain ETFs provide public market exposure to the underlying technology that supports cryptocurrencies like Bitcoin and Ethereum. 

But blockchain’s potential can extend far beyond crypto, and enable technologies like digital IDs, guaranteeing copyright and royalty protection, ensuring food safety, and verifying wills and inheritances.

What is Blockchain?

Blockchain is a public ledger technology for transactional applications that establish trust, accountability, and transparency.

It is a specific kind of database that stores information in “blocks” that get chained together.

Blockchain technology can record transactions between two parties efficiently and in a verifiable and immutable way.

Bitcoin employs a “decentralized” version of blockchain that puts the network users in charge instead of a central authority.

This means that Bitcoin is powered by a distributed network of nodes spread around the world, and not vulnerable to a single point of failure.

The nodes that power the network agree that a transaction is accurate and that information is copied to on each node.

The nodes can cross-reference each other to detect an incorrect transaction on the network, such as double-spending, and pinpoint the exact node with the false data.

Decentralization makes Bitcoin antifragile and censorship resistant. 

However, not all blockchains are decentralized like Bitcoin. Some are less decentralized, like Ethereum, and some are private, centralized versions that operate under a single roof. 

Now that we have a little background on blockchain technology, let’s see the best blockchain ETF to invest in.

KOIN tracks an index that uses artificial intelligence to select global stocks with a current or future economic interest in blockchain technology.

The index’s proprietary algorithm scans large amounts of textual data from online media platforms and databases.

These companies are then separated into four categories: cryptocurrencies payees, mining enablers, solution providers, and cryptocurrency users.

Each of these categories is allowed up to 15 holdings in the ETF. Each category capped at a total allocation of 40% and individual companies maxed at 7% of the fund.

KOIN provides ample exposure to semiconductor and FAAMG stocks.

Blockchain ETFs FAQs

What is the Best Blockchain ETF?

BLOK has been the best performing blockchain ETF in recent years and has the highest assets under management by more than double the next competitor. Additionally, the ETF has benefited from its large allocation to Square, one of the best-performing stocks in recent years. However, the Global X Blockchain ETF (BKCH) is probably the best blockchain ETF.

You will not find any publicly traded ETFs that track specific cryptocurrencies, but you can invest in companies that build crypto solutions or infrastructure. For example, Marathon Digital Holding is one of the first Nasdaq-listed cryptocurrency mining companies. 

What is the Best Way to Invest in Blockchain Technology?

We recommend diversifying into the highly competitive space by choosing an ETF such as BKCH, BLOK, BLCN, KOIN, or LEGR. While the expense ratios are higher for this kind of niche exposure, you will be rewarded nonetheless by the inevitable adoption of blockchain.

Can I buy a Bitcoin ETF?

You can buy a bitcoin futures ETF today under the ticker symbols BITO or BTF. The Grayscale Bitcoin Trust (GBTC) is another way to gain public market exposure to bitcoin. This fund pools investors’ money and buys bitcoin on their behalf. GBTC serves as a placeholder until the SEC approves a bitcoin spot ETF.

Can You Buy Blockchain Stock?

Yes, there are several publicly-traded blockchain and mining stocks. Some of the best mining stocks include Core Scientific (CORE), Hut 8 Mining (HUT), Argo Blockchain (ARBK), Riot Blockhain (RIOT), and Marathon Digital (MARA).
