Investing in Cryptocurrency: TIGER 21 Member Perspectives

In October 2021, the price of Bitcoin passed $66,000 for the first time. This peak came on the heels of the debut of the first U.S. Bitcoin-linked exchange-traded fund, ProShares Bitcoin Strategy ETF, all of which indicates yet another spike of interest around investing in cryptocurrency.

This renewed interest in investing in cryptocurrency has also registered in other venues, including Google searches. The terms “Bitcoin” and “cryptocurrency” have enjoyed significant spikes of their own in the last year, according to Google Trends. Search interest for the term “Bitcoin” hit highs in January and May and then settled in at 58% higher in October 2021, as compared to October 2020. Searches for the term “cryptocurrency” increased twelvefold in the last 12 months, revealing greater interest in the concept that goes beyond Bitcoin.i

A recent TIGER 21 Member poll revealed that our high-net-worth community is divided on the topic of investing in cryptocurrency. 27% of respondents were bullish on crypto, while a similar percentage, 28% were bearish. The majority of the community remained neutral.  However, it is evident that there is increasing interest in cryptocurrency as the same question was asked of Members three years earlier and results showed that 15% were bullish back then compared with 27% today while 52% were bearish vs. 28%.

TIGER 21 Member Poll:

Are you bullish, bearish, or neutral on the cryptocurrency market?
27% – Bullish          28% – Bearish         45% – Neutral

Additionally, fewer than one-third of TIGER 21 Members have initiated or increased their cryptocurrency investments in the three-month period prior to the poll:

Have you initiated or increased on investment in cryptocurrency in the last three months?
30% – Yes               70% – No

Given the rising interest in crypto overall, we also polled the TIGER 21 community of high-net-worth investors and entrepreneurs to understand which areas Members favor for investing in cryptocurrency. Ethereum and Bitcoin were the most popular, followed by crypto funds and alternative coins:

To get some additional perspective, we gathered three Members of TIGER 21’s Crypto Member Network, each of whom are heavily invested in the crypto space. In a discussion facilitated by Nashville TIGER 21 Chair, Jeff Hays, these three Members shared the following insights:

TIGER 21 Member David Bailey, Founder and CEO of BTC Inc, is all in on Bitcoin.

In his words: “In 2018, I made the ideological decision to refocus my energy solely on Bitcoin. For me, Bitcoin is really about investing into human potential—investing into what free money can do for the world.”  

TIGER 21 Member Andy Sack, Managing Partner at KeenCrypto LLC, is also enthusiastic about Bitcoin, as well as Ethereum and a few alternative coins:

“I’m very bullish on both Bitcoin and Ethereum. My personal assessment is that the wind is shifted in favor of Ethereum. I like the Ethereum alternatives as well—Solana and Avalanche, to name two.”  

TIGER 21 Member Sherry Witter, Managing Partner, Co-Founder & CIO at The Witter Family Office, has a number of different areas she’s invested in:

“Bitcoin obviously is a basic staple. I also like Litecoin, Ethereum, and Ripple, along with a lot of other coins. Each coin has its own purpose and there are some great funds out there as well.”  

Let’s take a deeper dive into the investment opportunities that most interest the TIGER 21 community.

Ethereum / Ether (ETH)

TIGER 21 Popularity Index: Highest at 32%

Launch Date:
Circulating Supply of ETH as of 10/27/2021:
118,100,808.06 ETH
Maximum Supply of ETH:
No upper limit

Conceived in 2013 by programmer Vitalik Buterin and launched in 2015, Ethereum is a blockchain network designed to power both its cryptocurrency, Ether (ETH) and decentralized apps (dApps). Its goals? Financial services untethered from banks and financial institutions, a powerful peer-to-peer network and a private internet that’s not controlled by any government or company.iii

Fast Facts About Ethereum / Ether (ETH):

  • Unlike Bitcoin, there’s no upper limit on the number of Ether that can be mined. However, the yearly available supply for mining is capped at 18 million ETH.
  • One game built on the Ethereum platform, CryptoKitties, became so popular that it clogged the entire Ethereum network. The app’s surge in popularity, which allows users to purchase, breed, and sell virtual cats, offers a peek at the potential for the metaverse and the role blockchain networks will play in creating that arena.
  • Ethereum is becoming the digital currency of choice for purchasing NFTs, with a piece called “The First 5000 Days” by Mike Winkelmann, known professionally as Beeple, going for more than $69 million in Ethereum.iv

The biggest thing that I’m looking for in a cryptocurrency is: Does it have a vibrant community of really smart builders doing cool things? I think Ethereum checks that box.

Bitcoin (BTC)

TIGER 21 Popularity Index: Second-highest at 31%

Launch Date:
Circulating Supply of BTC as of 10/27/2021:
18,856,050.00 BTC
Maximum Supply of BTC:
21 million

Invented in 2008 by an unknown person (or group of people) going by the name Satoshi Nakamoto, Bitcoin was designed as a “purely peer-to-peer version of electronic cash” according to the original white paper written by its founder. It quickly became the most commonly known cryptocurrency.

Fast Facts About Bitcoin (BTC):

  • El Salvador adopted Bitcoin as legal tender in October 2021. Today, the government holds 1,120 Bitcoin, worth more than $68 million as of late
  • Estimates suggest that 20% of Bitcoin—around 3.7 million—are locked in wallets that their owners no longer have access to.vii
  • The last Bitcoin will be mined in 2140.viii The network currently incentivizes miners to power the blockchain with a Block Reward in Bitcoin. Additionally, users can add transaction fees to incentivize miners. Once there are no more Bitcoins to mine, the reward system is expected to shift toward solely transaction fees.ix

Bitcoin in particular has established itself as the leading digital currency in the world. I believe that Bitcoin is a fantastic hedge against the monetary systems and, specifically, inflation.

Cryptocurrency Funds

TIGER 21 Popularity Index: Third-highest at 21%

A cryptocurrency fund offers the opportunity to invest in cryptocurrency without buying or selling any actual coins. In this field, you’ll find options such as:

  • Index Funds – Funds like the Bitwise 10 Crypto Index Fund (BITW), which tracks the total return of the 10 most highly-valued cryptocurrencies, are a simple way to spread an investment across a number of coins, while betting on the future of crypto as a whole. Other funds may focus on companies leveraging cryptocurrency or blockchain technology as a whole, offering investors the opportunity to bet on the future of the arena.
  • Exchange Traded Funds (ETFs) – With the recent arrival of the ProShares Bitcoin Strategy ETF (BITO) and the Valkyrie Bitcoin Strategy ETF (BTF), cryptocurrency ETFs are getting more attention than ever. Although ETFs are attractive to investors who don’t want to jump through the hoops of owning cryptocurrency directly, the annual fees can be high.

There’s so much opportunity at whatever level you want to invest in, whether you want to invest in venture capital, invest into the projects directly, or invest in crypto funds.
