You don’t need thousands of dollars to buy cryptocurrencies. Many platforms allow you to buy fractional amounts, so $100 is enough to open a position, learn how the market works, and then decide if crypto belongs in your portfolio.
First, get your mindset right. Starting with $100 is best viewed as a way to gain experience with little risk, not a fast track to wealth.
Cryptocurrencies can be exciting and chaotic. Prices can vary dramatically in a matter of hours and bad decisions are quickly punished. It’s not for everyone.
But starting with $100 can work in your favor. It gives you room to learn the ropes without putting too much on the line.
However, before you buy anything, make sure your financial bases are covered. If losing most of that $100 would really mess up your finances, you shouldn’t use it to buy cryptocurrency.
Experts generally recommend creating an emergency fund and paying off high-interest debt before investing.
Starting with $100 allows you to buy exposure and experience. You are learning how to execute a trade and monitor a position, and perhaps most importantly, how to react emotionally when your investment goes up or down.
That mindset is important because people who expect overnight profits are often the same people who tend to panic and sell after the first nasty dip.
“Having unreasonable expectations will typically lead to disappointing results,” said Adam Blumberg, CFP and managing partner at Protocol Wealth in Denver.
Finally, be honest about your risk tolerance. Cryptocurrencies are a market where crashes, exchange failures, hacks, and liquidity issues are part of the deal. Again, it’s not for everyone.
Are you still on board? Here’s how to get started.
Step 1: Get informed and be clear about your objectives
You don’t have to become a technical expert to buy cryptocurrencies. But it is beneficial to know the basics.
Start by learning a few key concepts: what cryptocurrency is, how buying and selling works, what a wallet is, and why cryptocurrencies are generally riskier than traditional investments, like stocks or mutual funds.
Before you start, it is also advisable to be clear about why you are buying cryptocurrencies.
“Why you invest will often determine your expectations and behaviors,” Blumberg said.
Is this 100 dollars just an experiment? Are you planning to add small amounts over time? Do you want to hold the position for the long term or are you actively trying to trade?
Blumberg pointed out other reasons why people may invest in cryptocurrencies, including the desire for a certain uncorrelated return, a hedge against traditional finance, or because they believe in the value of a particular project.
“These various reasons will help you make rational decisions, such as leaving your position when you have reached your goal or when economic or market conditions change,” Blumberg said.

The number of places where you can buy cryptocurrency has skyrocketed in recent years. From dedicated exchanges to popular payment apps, you have options.
Here is an overview of the main ways you can buy cryptocurrency:
-
Centralized exchanges: These include platforms such as Coinbase and Binance. They are designed specifically for cryptocurrencies, so they generally offer the widest selection of coins and the most advanced cryptocurrency-focused tools. This can be an advantage if you want flexibility, but it also offers more opportunities to pursue obscure altcoins or trade more than you can afford.
-
Payment Apps: Apps like Cash App and PayPal allow users to purchase cryptocurrencies in a more familiar and simplified interface. These may be attractive if you already use the app and want a quick way to get into the market. The trade-off is usually higher fees on small purchases and fewer coins to choose from. If you’re only working with $100, it’s essential to keep fees in mind.
-
Brokers and Trading Apps: Some mainstream investment platforms, such as Robinhood, Interactive Brokers, and Public, also offer cryptocurrency trading. These can be convenient if you already invest there and want to keep your financial life under one roof. But it’s still important to compare rates, spreads and available currencies.
Most platforms allow you to purchase fractional amounts, so your $100 can still be invested without having to purchase a full coin.
If you are buying cryptocurrency for the first time, simplicity is important. A flashy app with endless charts, coin recommendations, or gamification features like exploding confetti when you make a trade may be exciting, but it may push beginners to trade too frequently. A boring, easy-to-use platform is usually the best option.

There are thousands of cryptocurrencies on the market and honestly, most of them probably aren’t worth your attention. Cryptocurrencies are full of meme coins, low-quality projects, and thinly disguised pump and dump schemes.
If you’re only starting with $100, there are good reasons to stick with established cryptocurrencies like bitcoin or ether.
Bitcoin and ethereum are still volatile, but they’ve been around longer, have broader adoption, and offer more liquidity than you’ll see in newer or more speculative tokens.
“At this point, over-diversifying across many different currencies doesn’t typically result in better returns, but it does add more risk,” Blumberg said.
Step 4 – Set up your account, deposit funds and place your first trade
Next, it’s time to set up your account. This typically involves entering personal information, verifying your identity, and linking a bank account or debit card.
Once your account is set up, you can deposit your funds and place your first trade. Review the purchase amount, check the fees, and make sure you understand what you’re buying before hitting confirm.
If you think you might want to continue investing over time, you might also consider setting up recurring purchases. This helps you practice dollar-cost averaging, which means investing a set amount at regular intervals instead of investing all your money at once. This can help you build a position gradually and smooth out your purchase price over time rather than trying to anticipate the perfect entry point.
You will not owe taxes for purchasing and holding cryptocurrencies. But sale crypto to make a profit, or exchanging one currency for another, is a capital gain and is considered a taxable event in the eyes of the IRS.
If you sell cryptocurrency in 2026 through a US exchange or broker, that platform must now send you and Send the IRS a Form 1099-DA that shows key details of the sale, such as the date of the transaction, the proceeds, and, in some cases, cost basis information.
That brings cryptocurrencies closer to the same type of tax filing that investors already know from Form 1099-B for stocks and mutual funds.
In the past, most cryptocurrency investors received little or no standardized tax reporting from exchanges, making it easy to underreport profits, “forget” trades, or assume the IRS wouldn’t connect the dots.
With Form 1099-DA, which was first released to consumers in calendar year 2026, there are fewer gray areas and a much clearer paper trail. So if you sell cryptocurrency, it’s more important than ever to treat taxes here as seriously as you would with stocks or other investments.
If your goal is long-term cryptocurrency exposure and you want to avoid taxable trades, an alternative is to purchase cryptocurrency-related exchange-traded funds in a tax-advantaged account, such as an IRA. In a traditional IRA, taxes are generally deferred until you withdraw the money, while qualified withdrawals from a Roth IRA may be tax-free.
There are currently only three types of cryptocurrency ETFs on the market (bitcoin, ether, and solano), but buying and selling them within an IRA will not trigger capital gains taxes like it would within a regular taxable account.

After putting your money in the market, the next step is mostly patience. Cryptocurrency prices can swing wildly in a single day, so don’t be surprised if your $100 goes up or down quickly.
“Be prepared to wake up in the morning to market movements, without always having a clear idea why,” Blumberg said.
This is why position size is important. Starting with $100 is smart because it limits the damage if things go wrong or you decide cryptocurrencies aren’t for you. If you end up liking the asset class and want more exposure later, you can always add it gradually.
It’s also smart to monitor your own behavior. If you’re constantly checking prices, chasing online advertising, or being tempted to buy and sell based on emotions, that’s a problem. The goal is to stay informed without reacting.
“Investors should keep their expectations and theses in mind when watching price movements,” Blumberg said.
Let the craft teach you something, build your confidence, and then decide what’s next.
