Where to buy Sui (SUI)

The two platforms, honestly compared

Sui is a relatively young Layer-1 with a fast, low-fee design — and both major Dutch exchanges list it. Because the network is young, the buying side is straightforward while the storage side changes quickly.

• Bitvavo — 400+ assets, volume-tiered fees, free deposits. The larger catalogue.
• Finst — flat 0.15%, no added spread, flexible staking. Cheaper default for most purchases.

What buying SUI actually costs

Free EUR deposits and withdrawals on both. Finst’s flat 0.15% beats Bitvavo’s 0.25% base taker fee for typical buys; Bitvavo’s tiers take over at volume. Withdrawals: Bitvavo charges only the Sui network fee (tiny), Finst adds a €2.50 baseline. If you plan to withdraw to a wallet, that baseline is the cost to budget for.

Worked example — a €1,000 SUI purchase:

• Finst: €1,000 × 0.15% = €1.50 in fees, no added spread.
• Bitvavo: €1,000 × 0.25% = €2.50 at the base taker tier.

Withdraw once to your wallet: Bitvavo charges only the Sui network fee (usually under €0.01); Finst adds its €2.50 baseline on top.

How to buy Sui step by step

1. Create an account on Bitvavo or Finst and complete ID verification.
2. Deposit EUR — free SEPA or iDEAL on both.
3. Place your order — market for instant execution, or a limit order at your price.
4. Decide whether to stake. Both platforms have run SUI in their earn programmes — availability changes, so check the current earn page in the app.
5. Withdraw to your wallet — Sui addresses start with 0x and look similar to Ethereum addresses, but they are not Ethereum. Always withdraw on the Sui network, never an EVM chain.

The young-network caveat

Sui’s wallet ecosystem is still maturing. Support in apps like Phantom and Trust Wallet is good, but the list changes regularly — verify current support before moving large amounts. See our best Sui wallet guide for the picks that hold up today.

Because Sui uses a different account model (objects rather than accounts) and the Move language, not every wallet that supports “Ethereum” can sign Sui transactions. The practical rule: use a wallet that explicitly lists Sui support, and check the official list before trusting a claim.

After you buy

An exchange balance is custodial — Bitvavo and Finst hold your SUI for you. For anything you plan to keep, withdraw to a self-custody wallet on the Sui network (never another network).

Send a small test amount first — SUI withdrawals are fast and cheap, so there is no reason to risk a full balance on a single confirmation. And keep the recovery phrase offline: with a young network, wallet software updates more often, and the phrase is the only thing that guarantees access across versions.

Who should buy on which platform

• One-time SUI buyers — Finst’s flat 0.15% is the cheaper route, and its staking product adds yield without lock-up if you want it.
• Frequent movers — SUI network fees are fractions of a cent, so Bitvavo’s network-fee-only withdrawals are effectively free. The €2.50 Finst baseline is avoidable by withdrawing from Bitvavo instead.
• DeFi or wallet users — SUI’s ecosystem changes quickly; buy on either platform but verify your wallet supports Sui before withdrawing a meaningful balance. A small test amount first is non-negotiable.
