Want to start investing in crypto with less than $10? We tested the top platforms for micro-investing — Coinbase, Transak, and Uniswap — comparing minimum purchases, fees, and ease of onboarding so you can start small without getting eaten by costs.
You don't need a thousand dollars to buy crypto. In fact, you don't even need ten. Micro-investing — putting in just a few dollars at a time — is one of the best ways to start building a crypto portfolio without risking more than you're comfortable with. The catch? Not every exchange lets you trade in tiny amounts without punishing you with fees.
We looked at three platforms that actually work for sub-$10 investments, comparing their minimum purchase amounts, fee structures, and how easy they are to get started with.
| Platform | Minimum Purchase | Best For |
|---|---|---|
| Coinbase | $2 1 | Absolute beginners, lowest barrier to entry |
| Transak | ~1 EUR minimum fee 2 | Buying crypto directly with Apple Pay / Google Pay |
| Uniswap | Varies by network gas fees 3 | People who already hold a small amount of ETH or stablecoins |
Coinbase is the most straightforward option for micro-investing. You can buy as little as $2 worth of crypto — that's the lowest minimum on any major exchange we've seen.1
Why it works for micro-investors:
The trade-off: Coinbase's fee structure isn't the cheapest for tiny amounts. You'll pay a spread plus a flat fee on smaller transactions, which means the percentage cost is higher on a $2 buy than on a $200 buy. But for learning and getting started, it's hard to beat.
Transak is a fiat-to-crypto on-ramp that many wallets and apps use behind the scenes. You can buy crypto directly using Apple Pay or Google Pay, and the fee starts at around 1 EUR minimum.2
Why it works for micro-investors:
The trade-off: The fee is 5.5% of the transaction amount (for non-EUR Apple Pay / Google Pay),2 which adds up. On a $10 purchase, that's $0.55 — not terrible, but not nothing. Best used when you want to jump into a specific wallet or dApp quickly.
Uniswap is a decentralized exchange (DEX) that lets you swap tokens directly from your own wallet. There's no account, no KYC, and no minimum trade amount set by the platform itself.3
Why it works for micro-investors:
The trade-off: The real minimum is set by network gas fees. On Ethereum mainnet, gas can be $5–$20+ per swap, which makes a $5 trade pointless. However, on Layer 2 networks like Arbitrum, Optimism, or Polygon, fees can be pennies. Uniswap's web app will automatically route your swap through the best available network.3
This one is best if you already hold a small amount of ETH or a stablecoin and want to trade into other tokens without giving up custody.
| Dimension | Coinbase | Transak | Uniswap |
|---|---|---|---|
| Minimum Entry | $2 1 | ~1 EUR fee 2 | Gas-dependent 3 |
| Onboarding Ease | Very easy (bank/card) | Easy (Apple/Google Pay) | Moderate (needs wallet) |
| Fee Structure | Spread + flat fee | 5.5% (Apple/Google Pay) | Network gas + 0.3% swap fee |
| Custody | Exchange (not your keys) | Depends on destination | Self-custody (your wallet) |
If you're brand new to crypto and want to buy $5 of Bitcoin to see how it feels: go with Coinbase. The $2 minimum and beginner-friendly interface make it the safest bet.
If you want to buy crypto instantly with your phone and send it to a wallet or app: Transak is your best bet, especially for small amounts where the 5.5% fee is manageable.
If you already have a wallet and want to trade small amounts of tokens without a middleman: Uniswap on a low-fee L2 network is the way to go.
