Where to buy Kaspa (KAS)

The two platforms, honestly compared

Kaspa is a young network with a distinctive BlockDAG design, and the two major Dutch exchanges were among the earliest European platforms to list it. Both offer KAS with SEPA/iDEAL deposits and MiCA authorisation.

• Bitvavo — 400+ assets, volume-tiered fees, free deposits. The larger catalogue, and the more established KAS trading venue of the two.
• Finst — flat 0.15%, no added spread, flexible staking. Cheaper default for smaller purchases.

What buying KAS actually costs

Free EUR deposits and withdrawals on both. Finst’s flat 0.15% undercuts Bitvavo’s 0.25% base taker fee for typical retail purchases; Bitvavo’s volume tiers win if you trade heavily. Withdrawals to your wallet: Bitvavo charges only the Kaspa network fee, Finst adds a €2.50 baseline. KAS network fees are small but vary with traffic — the Finst baseline is the fixed cost to budget for.

Worked example — a €1,000 KAS 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: only the Kaspa network fee (typically well under €0.10) on Bitvavo, or that plus €2.50 on Finst.

How to buy Kaspa 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 where the KAS lives — custodial until you withdraw it. If you plan to hold, decide your wallet before buying (step 5).
5. Withdraw to your wallet — Kaspa addresses start with kaspa:. KAS always runs on the Kaspa network; there is no chain-selection trap, but the address format is unique — never paste it into an Ethereum or Bitcoin withdrawal field.

The hardware-wallet reality check

Before you buy KAS in volume, know this: neither Ledger nor Trezor supports Kaspa natively in its main app. If cold storage is your plan, Tangem and OneKey^Sponsored are the hardware options that support KAS. That is the single most important thing to sort out before (not after) you buy — see our Kaspa wallet guide.

This is the opposite of most coins, where hardware support is a given. For KAS it decides your entire storage setup:

• Kaspium (mobile) or Kasware (browser) — free software wallets, good for everyday balances.
• Tangem (card) or OneKey^Sponsored (device) — the hardware route; Tangem is seedless by default (backup = additional cards), OneKey^Sponsored uses a standard recovery phrase.

Sort out which one you will use before the KAS arrives; a test withdrawal of a small amount beats discovering a compatibility problem with a full balance.

After you buy

An exchange balance is custodial — Bitvavo and Finst hold your KAS for you. For anything you plan to keep, withdraw to a self-custody wallet; see our Kaspa wallet guide and the step-by-step withdrawal tutorial.

Who should buy on which platform

• Buy-and-hold KAS holders — Finst’s flat fee is cheaper per purchase, and the €2.50 withdrawal baseline is a one-time cost if you withdraw once and hold. That combination is the cheapest route for a single position.
• Frequent withdrawers or DCA buyers — Bitvavo’s network-fee-only withdrawals win. If you dollar-cost-average monthly and move KAS off the exchange each time, the Finst baseline adds up to €30/year — the trading-fee difference rarely covers that.
• Hardware-wallet owners — because Ledger and Trezor lack native KAS support, sort out your Tangem or OneKey^Sponsored setup before buying. The exchange choice matters less than the wallet choice here.
