You may already have an investment portfolio, perhaps a mix of hand-picked stocks, mutual funds, and ETFs. Those options cover most of the market, but what about crypto? Known for its volatile price action, crypto can help propel an otherwise standard portfolio to new heights. However, that price volatility works both ways, and a crypto crash can erase your gains elsewhere. Strategy matters. In this guide, we’ll discuss how to build a crypto portfolio without the guesswork.
If you’re just getting started with crypto investing, it’s often safer to start with blue-chips, meaning time-tested investments in the crypto space, rather than the latest memecoin or the token for a new blockchain or decentralized application. We’ll explain why, but let’s start with allocations.
What percent of your portfolio should be crypto?
There isn’t a single correct answer to the question, “What percent of a portfolio should be crypto?” Financial advisors often suggest keeping it small. For a conservative investor, that might mean limiting crypto exposure to just 1% to 5% of investable assets: If your investment portfolio is worth $100,000, you might allocate $1,000 to $5,000 toward digital assets. This amount gives you a stake in the game, but it’s small enough that it won’t derail your retirement plans if the market turns against you.
Aggressive investors might take a different approach. If you have a high risk tolerance or a long time horizon, you might feel comfortable with 10% or more in crypto. However, now your picks matter more.
It’s possible that the cryptocurrencies you choose as an investment fall out of favor. Maybe a better solution comes along. Crypto markets are also famous for “winter” cycles, where prices can drop 60% or more from their highs. Decide whether you can handle that kind of decline without panic selling. At a 1% allocation, market turbulence won’t break your portfolio. At 15%, a crypto market mishap could wipe out years of gains in other areas of your portfolio.
Double-digit price moves in a single day aren’t uncommon in crypto. Ask yourself how much value you could lose in a day and still sleep soundly at night. If a sudden 20% drop in your crypto allocation’s value would make you anxious, your allocation is too high.
Crypto investing pairs high risk with potentially high rewards; don’t bet the rent or mortgage money. Fund your crypto investments with money you can afford to lose, or money you can lock away for years without needing it.
Establishing a foundation: The core crypto assets
The crypto space is more driven by hype than many traditional investments. You’ll never hear “to the moon” in the same sentence as bond funds. A common mistake for beginners is buying into the hype by jumping straight into the newest tokens or “memecoins.”
A safer strategy starts with a strong foundation built on core assets. In traditional finance, these are often called “blue chip” investments. In crypto, blue chips are the large-cap leaders that have survived multiple market cycles. They have proven utility and a large enough market to allow you to enter or exit a position easily.
Bitcoin and ethereum usually take the lead here. Let’s start with bitcoin.
Crypto blue-chips: Bitcoin
Launched in 2009, bitcoin (BTC) is often called “digital gold.” Investors see it as a store of value and a hedge against inflation, similar to how gold is seen as an inflation hedge. Scarcity is the driver behind this narrative. Bitcoin’s maximum supply is 21 million bitcoins. On the Bitcoin blockchain, users pay for transactions using bitcoin, which also creates demand for the asset.
Keep an eye on “bitcoin dominance.” You can find charts for BTC.D (bitcoin dominance) on leading crypto data sites, such as CoinGecko. This metric refers to the percentage of the crypto market controlled by BTC. As dominance falls, it means the broader crypto market is rotating to more speculative crypto investments. If BTC’s price falls as the market chases shinier new altcoins, there may be a buying opportunity for long-term investors.
Bitcoin has the largest market capitalization (the total value of all coins in existence) and the longest track record. Institutions, including investment banks and even some corporations, hold bitcoin on their balance sheets. That adoption provides a level of stability that newer coins lack. Newer bitcoin spot ETFs (exchange-traded funds) provide one way to gain exposure and help keep the BTC market vibrant.
Crypto blue-chips: Ethereum
Ethereum, launched in 2015, serves a different purpose. The Ethereum network acts as a global computer that runs smart contracts. These are self-executing contracts that act like conditional switches. If this happens, then do that.
Smart contracts enable developers to build decentralized applications (dApps), ranging from lending platforms and decentralized exchanges (DEXs) to NFT marketplaces. Because so much of the crypto economy runs on Ethereum, its token, ether (ETH), becomes a utility token. To interact with a smart contract or dApp, users need ETH. This demand for ETH helps create a floor for the price. However, Ethereum isn’t the only smart-contract blockchain. A competing chain could affect demand for ETH.
Many crypto investors allocate the bulk of their crypto portfolio, often 50% or more, to these core assets. Although you’ll still see price volatility, BTC and ETH are less likely to go to zero than an unproven project or memecoin. Starting with the two largest cryptocurrencies by market cap gives you a base to build on before diversifying into other crypto assets.
Other blue-chip cryptos to consider
Crypto blue chip lists often include cryptocurrencies such as Solana (SOL), BNB Smart Chain (BNB), Chainlink (LINK), and Aave (AAVE). You’ll also see several chains that show promise or have a longer market history, but which may or may not have an active user base. Let’s look at some contenders.
-
Solana (SOL): The Solana blockchain was created to address the speed and cost challenges of existing chains, such as Bitcoin and Ethereum. The SOL token serves as network fuel, creating demand for it. However, it’s also important to consider use cases. The Solana blockchain has become popular among memecoin traders and has only recently begun to see growth in newer use cases, such as decentralized infrastructure applications.
-
BNB Smart Chain (BNB): The BNB Smart Chain (BSC) began as a blockchain centered around the Binance crypto exchange. Over the years, it has become a popular alternative to Ethereum due to its lower costs and faster transactions. BSC’s native token (BNB) has seen spectacular price growth since launch, and automated token burns (removing tokens from circulation) help balance supply with demand.
-
Chainlink (LINK): Several of the cryptocurrencies we’ve mentioned support smart contracts. Chainlink enables these smart contracts to use trusted data from the outside world as triggers. This data could be virtually anything. Sports scores. The weather in London. The price of gold. However, Chainlink is also paving the way for cross-chain compatibility. Chainlink’s Cross-Chain Interoperability Protocol (CCIP) enables assets on chain A to be used on chain B without tedious and tax-triggering selling and buying. The LINK token powers Chainlink’s network of “oracles” that provide data.
-
Aave (AAVE): The Aave lending and borrowing platform allows users to lend to earn a yield or borrow against crypto assets, accessing the value without selling. Although several competing platforms now exist, Aave remains the king of the hill for lending protocols. The AAVE token serves as a governance token. AAVE holders can vote on protocol changes. However, Aave’s excess profits are used to fund token buybacks, which can boost the token’s value, much like a stock buyback reduces available supply.
Branching out: How to diversify a crypto portfolio
Blue-chips may still see significant gains in the years ahead, but the 100x, 1,000x, or even 10,000x gains in their histories aren’t as likely going forward. These are largely mature assets, and for some investors, the hunt stops there. But if you want the possibility of larger returns, along with the risk of bigger declines, you’ll likely need to dig further in the altcoin bargain bin. The term “altcoin” (alternative coin) refers to any cryptocurrency that isn’t bitcoin. Often, the simplest way to diversify beyond the top cryptocurrencies is to look at sectors. For example, if you think blockchain-powered AI will be big, you can investigate tokens in that specific sector of the market. Let’s look at some groupings to consider.
Sector Diversification
Just as a stock portfolio might have technology, healthcare, and energy stocks, a crypto portfolio should have exposure to different sectors. If you only hold Bitcoin and Ethereum, you are exposed to the success of those two networks. By branching out, you capture potential growth in other areas.
Layer 1 Competitors
A Layer 1 blockchain (L1) handles its own consensus, meaning the network doesn’t depend on an external network to validate and secure transactions. Alternative Layer 1 chains include Avalanche (AVAX), TRON (TRX), Hyperliquid (HYPE), and Cardano (ADA), all of which support smart contracts, similar to Ethereum. Assets like Kaspa (KAS) and Bitcoin Cash (BCH) provide faster alternatives to Bitcoin. You can also consider crypto assets that target cash settlements, such as XRP and Stellar (XLM). These chains are used by financial institutions to send money across borders.
Much like investing in individual stocks, you’ll have to do your own research (DYOR), to determine which assets fit your strategy and how viable they are in an evolving market.
Decentralized Finance (DeFi)
This sector aims to recreate traditional financial systems, but without banks or other middlemen. Many DeFi protocols issue their own tokens that serve as governance (voting) tokens or provide utility or access within the protocol. Aave, mentioned in the blue-chip section, offers one example. UNI, the token for the Uniswap decentralized exchange, offers another.
Decentralized Physical Infrastructure Networks (DePIN)
Another growing sector called DePIN aims to decentralize many of the services we use today, such as file storage, broadband access, and access to Graphics Processing Units (GPUs) for AI and other use cases. These projects use tokens to reward providers or grant access to services. Some examples include Helium Network (HNT), Render Network (RENDER), Venice (VVV), Filecoin (FIL), and Arweave (AR).
Although not as well-known as blue-chip tokens in the sector, smaller tokens in emerging sectors may offer higher returns. On the other hand, they might go to zero if the demand isn’t there. More than half of all cryptocurrencies ever launched are now dead.
Market correlation risks
In a traditional portfolio, when stocks go down, bonds often go up. In crypto, asset movements tend to be highly correlated, and bitcoin still steers the ship. However, other crypto assets are often more volatile than bitcoin. A 5% price move in BTC might translate to a 10% move for the altcoins in your portfolio. Keep this in mind when making your allocations.
Weighting your speculative bets
Often, new investors allocate equal amounts to each coin in their crypto portfolios. This approach weights riskier investments with the same allocation as well-established blue-chips. A safer approach would be to account for risk in your speculative bets by using smaller allocations. For example, you might allocate only 1% to 5% of your total crypto portfolio to any single high-risk asset. This way, if a coin gains 10x in value, it boosts your portfolio. If it goes to zero, it’s a lesson rather than a catastrophe.
Ways to gain exposure to crypto
You have several options when adding crypto to a larger portfolio. You’ll find a broader range of coins and tokens when using an exchange like Coinbase. However, crypto ETFs and even decentralized exchanges provide ways to gain exposure.
-
Centralized exchanges: Coinbase and other well-established crypto exchanges provide an easy on-ramp for crypto investors. Typically, you can choose from hundreds of cryptocurrencies, including many that may have a greater potential for appreciation compared to market-leading blue chips. The exchange manages a crypto wallet on your behalf to secure your crypto after you make a purchase. For long-term storage, consider withdrawing your holdings to a non-custodial crypto wallet that you control.
-
Crypto spot ETFs: Although the selection is growing, crypto ETFs don’t offer as wide a selection. What they do offer is convenience. You can invest in crypto alongside your other equities and funds in a traditional investment account and the fund manages custody, often using Coinbase as a custodian. Be aware that some crypto ETFs use futures positions to gain exposure. Spot ETFs, a newer alternative, track the market price more accurately. In this case, the fund owns the actual asset rather than derivatives. Expect a wide range of exchange-traded spot crypto funds for bitcoin and ethereum. Solana and XRP are also available as spot ETFs.
-
Direct acquisition: You can also acquire crypto through other methods, such as receiving payments in crypto or buying on a decentralized peer-to-peer (P2P) exchange, such as Bisq. Decentralized exchanges of this type act as a marketplace for buyers and sellers. Some investors prefer P2P trading for privacy reasons. You’ll need a non-custodial crypto wallet to manage your holdings. The exchange doesn’t manage a wallet on your behalf.
Strategies for acquisition and trading
Although crypto prices often follow patterns seen in technical trading, price moves can be sudden, which makes it challenging to time the market. For most investors, a disciplined approach often works better than trying to read the market tea leaves.
Dollar-Cost Averaging
Dollar-cost averaging refers to investing a fixed amount of money at regular intervals. For example, you might buy $100 worth of bitcoin every Monday morning. This approach naturally optimizes for lower prices; you’ll buy more of a given asset when prices dip and less when the market is rising. For investors of any experience level, dollar-cost averaging is an acknowledgment that we don’t know exactly what the market will do over the next 10 minutes or 10 days. Dollar cost averaging smooths out the price volatility for which crypto has become famous.
Holding vs. trading
Given the price volatility, trading is often more challenging when crypto is involved. A sudden 5% or 10% move isn’t uncommon, but it can push many traders to sell some or all of their positions, only to watch the market recover in the following hours or days.
You’ve likely heard the term “HODL” in the crypto community. It originated as a typo for “hold,” but it has now become a mantra: “Hold On for Dear Life.” The philosophy is simple: Do your own research and choose assets you think will appreciate in the long term. Ignore the short-term price swings, and if you’re investing for the long-term, buy more. Dollar-cost averaging handles this automatically.
Active trading requires a different mindset, time to monitor the market, and the ability to stay up to date with the news. Trading involves analyzing technical indicators, order books, and market sentiment to make frequent trades. While profitable for some, most day traders lose money. That stat comes from stock and forex markets, but it holds true for crypto traders as well. You’re competing against algorithms and professional market makers. Transaction fees on exchanges can also eat into profits quickly. Unless you have the time and desire to learn technical analysis, a “buy and hold” strategy is generally considered safer for building wealth.
Safety, execution, and liquidity
Where you buy matters. Platforms like Coinbase and Kraken are well-respected in the industry, but the industry has also had its share of exchanges that went bankrupt, suffered breaches, or simply disappeared overnight. The DYOR maxim applies when choosing a buying platform as well.
When selecting a platform, also consider liquidity. Liquidity refers to how easily you can buy or sell an asset without affecting its price. High-liquidity assets like BTC and ETH have tight spreads because there are more buyers and sellers. Spreads refer to the difference between the lowest sell price and the highest buy price. Low-liquidity assets can have wide spreads; something to keep in mind if you diversify into smaller speculative tokens. You might end up paying more than expected.
Storing your crypto
Cryptocurrency exchanges offer a convenient way to buy crypto with fiat currencies like the U.S. dollar. The exchange manages a crypto wallet for you, and you access your account via a username and password. Although designed to be beginner-friendly, this custody arrangement is better suited for short-term trades. When building a crypto portfolio for the long term, it’s safer to withdraw your crypto to a self-custody wallet you control.
A crypto wallet is an app (or a device paired with an app) that stores the private keys that control your crypto on a blockchain. Using a self-custody wallet, also called a non-custodial wallet, gives you control over your crypto and safeguards against exchange risks, such as breaches or exchange insolvency. Your crypto is yours. When it’s time to sell, you can transfer your crypto back to an exchange to make your trade.
Crypto portfolio rebalancing
Buying the right assets is only the first step. Over time, market movements will skew your carefully planned percentages. If you allocated 50% to bitcoin and 20% to a smaller altcoin, a sudden spike in that altcoin’s value might push its weighting to 40% of your portfolio. Suddenly, you are taking on much more risk than you intended. This is where rebalancing becomes important.
Rebalancing is the process of selling assets that have grown too large a portion of your portfolio and buying assets that have shrunk. You are effectively “selling high” to “buy low.” If your altcoin position doubles, you might sell to lock in some of the profit and move that value back into bitcoin, cash, or perhaps another opportunity you’ve identified. This strategy allows you to take profits rather than watching them evaporate during a correction.
You can rebalance on a schedule, perhaps once a month or once a quarter, or you can rebalance based on thresholds. For example, you might decide to adjust your portfolio only if an asset’s weight moves more than 5% away from your target. It may feel counterintuitive to sell an asset that is rapidly gaining value, but it protects your gains and uses rules you define to prevent emotional trading decisions. You don’t have to divine the exact market top; you’re taking profits on your own terms.
Conclusion
Allocation structure, discipline, and risk management are all key to building a crypto portfolio. As a first step, determine how much of your total wealth you can afford to risk and what percentage of your total investment portfolio should be in crypto.
Many investors build their crypto portfolios around time-tested assets like bitcoin and ethereum. Some stop there, which can limit your upside potential. Consider diversifying with tokens in sectors that might outperform your blue-chip picks. However, when you diversify, always allocate in proportion to risk. No one has a 100% success rate in investing, and more than half of all cryptocurrencies ever launched are now defunct; some of your picks may go to zero.
You’re your own ambassador in crypto. There’s no investment broker to handle the details (or blame when things go sideways). You have to look out for your own best interests. Secure your assets with a crypto wallet you control and remember to rebalance your portfolio periodically. Stay curious. There are always new opportunities in crypto, but never invest money you can’t afford to lose.
