How to Buy Sui (SUI) in 2026: Step-by-Step Guide
Sui is one of the youngest major blockchains, created by former Meta employees. We explain how it works, where its weak spots are and how to buy SUI step by step.
What Is Sui
Sui was developed by Mysten Labs, a company founded by former Meta employees from the Diem project. The main network went live in 2023. Like Aptos, Sui uses the Move language, but its own version of it.
Its main feature is the “object” model: every asset on the network is a separate object with its own owner. Simple transfers can be processed in parallel, without a shared queue, so the network is fast and cheap. The SUI coin is used for fees, staking and voting. The maximum supply is 10 billion SUI.
Sui Risks
- Unlocks. The team’s and investors’ shares enter circulation on a schedule.
- Decentralization questions. In 2025, after a major exchange on the network was hacked, validators froze part of the stolen funds — this sparked debate about how independent the network really is.
- A short history and tough competition with Aptos, Solana and others.
- High volatility.
How to Buy Sui (SUI) on an Exchange
- Account. Signing up on a major exchange takes a couple of minutes. Guide: how to open a crypto exchange account.
- Security. Complete KYC verification, then set up 2FA and an anti-phishing code. Do this before your first deposit.
- Fund your account. Top up your balance in USDT: via P2P from another user or with a card. Step by step: how to fund your account via P2P; why USDT specifically: what is USDT.
- Buy. Go to spot, pick the SUI/USDT pair and place a limit order slightly below or at the current price. Why it beats a market order: limit vs. market orders.
- Protect the trade. If you’re trading rather than accumulating, set a stop-loss right away. In Aspiro Trade, signals on 45 assets come with entry, take-profit and stop-loss levels already set.
- Storage. Coins you plan to hold for years are better kept in your own wallet than on an exchange. Withdraw SUI on the Sui network; it has its own addresses, and sending from another network won’t work.
Storing SUI: Two Options
| Exchange | Your own wallet | |
|---|---|---|
| Control over the coins | The exchange | You |
| If you forget your password | Support can restore access | Without the seed phrase, access can’t be recovered |
| If the exchange goes bankrupt | Your coins are at risk | Not affected |
| What you need | Just an account with 2FA | A wallet that supports Sui |
Our partner link. If you decide to open an OKX account, please sign up through it: it’s free for you and doesn’t change any terms. If you trade, the exchange pays Aspiro a referral bonus, which goes toward developing our apps and the free Aspiro Academy. We have no access to your account, funds or trades.
- You don’t need to buy a whole SUI — you can start with a small amount.
- Check the network and address on every withdrawal.
- Set the stop-loss before you enter a trade, not after.
Frequently Asked Questions
How is Sui different from Aptos?
Both networks were created by people from the Diem project and use Move. But Sui stores data as separate objects, while Aptos uses accounts, and this changes how the network processes transactions.
How much SUI is there?
The maximum supply is 10 billion coins. A significant part enters circulation gradually, according to an unlock schedule.
Can I stake SUI?
Yes, through an exchange or by delegating to a validator. There’s no guarantee of income, and it may not cover a drop in price.
