What to Know About Investing in Crypto Exchanges

A conversation with cryptocurrency expert Ethan Vera

With investors more bullish than ever on cryptocurrency, interest in the decentralized virtual currency continues to grow. For those who are relatively new to investing, crypto can seem daunting, even downright scary.

Cryptocurrency is a decentralized digital or virtual currency, secured by cryptography, making it virtually counterfeit-proof. It is limited in its supply, which helps give crypto value and makes it nearly impossible to counterfeit or double-spend.

Although legitimate cryptocurrencies can offer solid returns, cryptocurrency fraud has nearly doubled during the pandemic. In a preliminary report for the third quarter (Q3) of 2021, the Federal Trade Commission (FTC) found that fraudulent cryptocurrency payments cost victims $200.8 million in total.

Today, most buying and selling of cryptocurrency takes place through a cryptocurrency exchange, much like a stock exchange for securities. An exchange is an intermediary between a buyer and a seller of Bitcoin, the most well-known cryptocurrency, or any other type of cryptocurrency.

To help remove some of the mystery surrounding cryptocurrencies as an investment, Investopedia spoke with Ethan Vera, co-founder of Luxor and Viridi Funds as well as a member of Investopedia’s Financial Review Board. Vera’s expertise in cryptocurrency and crypto mining stems from his immense experience in the space. Investopedia spoke with Vera about crypto in general and how to access cryptocurrency as an investment. Our edited conversation follows.

"Of interest these days, Bitcoin is considered an excellent inflationary hedge.” — Ethan Vera

Reasons to Invest in Crypto

Investopedia: First, what makes cryptocurrency a good investment?

Vera: Let’s start with an example. In terms of investing, among cryptocurrencies, Bitcoin is the most stable and least volatile digital currency. It should be thought of in a similar manner to a long-term equity investment, not like fixed income. In that respect, Bitcoin is similar to a large-cap stock. Of interest these days, Bitcoin is considered an excellent inflationary hedge. As a commodity, Bitcoin is the most regulated cryptocurrency and the least risky, since Bitcoin’s protocols limit risk.

Investopedia: Aside from Bitcoin, what are some other cryptocurrencies, and what makes them worth considering?

Vera: The Ethereum blockchain network and its cryptocurrency, Ether, are popular because of the applications being built on top of it. Uniswap and Solana are other exchange and protocols gaining significant volume. Many altcoins, meaning cryptocurrencies other than Bitcoin, function as more of a technology play. Their innovations are really interesting; however, sometimes this is at the expense of decentralized governance.

The Danger of a 51% Attack

Investopedia: What do you mean by disruption?

Vera: One type is a hypothetical, for now, disruption known as a 51% attack. A 51% attack is when a group of miners controlling more than 50% of a network’s mining hash rate or computing power could prevent new transactions, reverse transactions, and double-spend coins. While it might not destroy the system, it could cause a lot of damage.

Obviously, the best way to prevent a 51% attack is to make sure nobody controls more than 50%. In Bitcoin mining, the cost and difficulty of hardware and energy procurement make this very unlikely. The network is very resilient to this type of attack.

The Role of an Exchange

Investopedia: Can you give us a short background on the history of how exchanges came into being?

Vera: Sure. In the early days, there were no exchanges. The general public didn’t even know about Bitcoin. The only way to obtain Bitcoin was by mining it yourself or through a peer-to-peer transfer with someone else. Then came over-the-counter (OTC) exchanges, at first unregulated, then more and more regulated as time went on. In 2015, the Coinbase exchange was born. Today, Coinbase is among dozens of exchanges operating in the U.S. and globally.

Investopedia: What do investors need to know about exchanges?

Vera: First of all, the major centralized exchanges, like Coinbase, Kraken, and others, are heavily regulated. The first thing to know before choosing an exchange for investors is to check if it can legally operate in your jurisdiction. Even with well-regulated legal exchanges, don’t put all of your investment in one exchange at the same time. In other words, spread out your investments and hold as much as possible in cold storage. There are many bad actors in crypto, and the best way to avoid them is to deal with well-known regulated exchanges, your own wallets, and trusted custodians.

Cryptocurrency, by its nature, attempts to be a decentralized type of currency, meaning that it is not a government- or company-controlled currency but a peer-to-peer type of money. Exchanges can be centralized or decentralized in how cryptocurrencies are managed and traded.

Centralized vs. Decentralized

Investopedia: Can you explain the difference between centralized and decentralized crypto exchanges?

Vera: Centralized exchanges, like Coinbase, are regulated, easy to use, reliable, and allow trading of digital for fiat currencies (i.e., dollars). However, they require you to trust your counterparty. Decentralized exchanges are controlled by the users, sometimes at the expense of user experience.

Newcomers to crypto should start with centralized exchanges, due to the ease of use, and then experiment with decentralized ones. There are plenty of options, including trading actual crypto, ETFs, and investing in mining companies, including mining ETFs. One example is the RIGZ mining ETF from Viridi.

Level of Involvement

Investopedia: What are some questions investors should ask themselves before selecting an exchange?

Vera: First, what percent of my portfolio do I want to allocate to cryptocurrency? It should be some but certainly not an overwhelming amount. The best answer is “not more than you can afford to lose.”

Many experts suggest that no more than 2%–3% of your portfolio should be allocated to cryptocurrency.

In terms of cryptocurrency, remember that Bitcoin is the safest, so I would definitely suggest Bitcoin until you have a deeper understanding of this type of investing. Keep in mind that this part of your portfolio is probably long term, just like other equities, 10, 20, or 30 years. Ask yourself, how involved do I want to be? Casual, moderate, deep dive? That has an impact on the type of investing you want to do. Mining, for example, is more complicated than buying cryptocurrency or an ETF.

Where to Get Help

Investopedia: What about support and information? Where do investors go to avoid these bad actors?

Vera: Most major exchanges offer very good support for investors, including advice. Any reputable exchange has a good support network and can help even the most novice investors. It’s important to do research on your own and not pay for consulting from unknown sources.

Information and advice are available for free on the internet. One example is www.lopp.net, run by Jameson Lopp, a self-described “professional cyberpunk” whose primary interest is Bitcoin security and making it easier for people to “take custody of their bitcoin and manage their private keys.”

Closing Thoughts

Investopedia: What else should potential crypto investors know?

Vera: Keep in mind that like any type of investing, with crypto, the higher the potential reward, the riskier the investment. This is the reason for keeping your investment in crypto manageable, sticking with trusted exchanges, and getting as much education as possible, no matter your level of involvement.

Another important concern is taxes. You need to know your tax obligations when it comes to cryptocurrency, especially when working with a well-regulated centralized exchange. It’s important that you report all realized capital gains just as you would with any type of investment.

What’s the difference between a centralized and decentralized crypto exchange?

According to crypto expert Ethan Vera, centralized exchanges like Coinbase are regulated, easy to use, reliable, and allow trading of digital for fiat currencies (i.e., dollars). Decentralized exchanges are anonymous and less prone to hacking, but they don’t let you trade for fiat and are complicated.

What percentage of my portfolio should be in crypto?

Vera says the best answer is “not more than you can afford to lose.” Beyond that, most experts suggest it should be less than 5%, along the lines of 2%–3%.

What’s a 51% attack?

A 51% attack in the crypto world is a hypothetical type of disruption in which a group of miners control more than 50% of a network’s mining hash rate or computing power. In such a scenario, they could prevent new transactions, reverse transactions, and double-spend coins. It might not destroy the system, but it could cause a lot of damage.
