Where to buy Stacks (STX)

The two platforms, honestly compared

STX is listed on both major Dutch exchanges, so the buying decision comes down to fees and what you plan to do after. Both are MiCA-authorised under the AFM.

• Bitvavo — the larger catalogue, volume-tiered fees (0.25%/0.15% base), free SEPA/iDEAL deposits.
• Finst — flat 0.15% with no added spread, free deposits, flexible staking across listed assets.

What buying STX actually costs

Deposits are free on both platforms, and EUR withdrawals are free too. Finst’s flat 0.15% beats Bitvavo’s 0.25% base taker fee for typical purchases; Bitvavo’s tiers win at volume. On crypto withdrawals, Bitvavo passes on only the Stacks network fee, while Finst adds a €2.50 baseline. If you move STX to a wallet to stack it, that withdrawal cost applies every time.

Worked example — a €1,000 STX 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 Stacks network fee on Bitvavo (a small fraction of a euro), or that plus €2.50 on Finst.

How to buy STX 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 you want to stack (the Stacks term for staking) — it changes where the STX should live.
5. Withdraw to a Stacks wallet — addresses start with SP or SN; use Leather or Xverse. Verify the address and send a small test amount first.

Stacking: the BTC-reward decision

Stacks has a genuinely interesting follow-up decision: stacking rewards STX holders in BTC. Exchange stacking is custodial and convenient; withdrawing to Leather or Xverse and stacking there keeps your keys with you — but locks your STX for one Bitcoin cycle (~2 weeks). See our Stacks wallet guide for the details.

The honest trade-off:

• Exchange stacking — no wallet setup, no lock beyond the cycle, but the exchange holds the keys and takes a cut.
• Self-custody stacking — full ownership and you choose your pool, at the cost of managing a wallet and reading the pool’s terms.

After you buy

An exchange balance is custodial. Stacks has a genuinely interesting follow-up decision: stacking rewards STX holders in BTC. Exchange stacking is custodial and convenient; withdrawing to Leather or Xverse and stacking there keeps your keys with you — but locks your STX for one Bitcoin cycle (~2 weeks). See our Stacks wallet guide for the details.

Who should buy on which platform

• Stackers — decide custody first: exchange stacking (simple, custodial) vs self-custody stacking (keys + ~2-week cycle lock). That decision matters more than the fee difference.
• One-time buyers — Finst’s flat 0.15% is cheaper for a single STX position.
• Frequent movers — Bitvavo’s network-fee-only withdrawals win if you move STX to a wallet regularly.

How stacking rewards actually land

Stacking rewards are paid in BTC (not STX), which surprises most buyers. The mechanism: Stacks settles batches on Bitcoin, and STX holders who lock their tokens during a cycle get a share of the BTC fees from that batch.

Two consequences worth planning for:

• Reward timing is cyclical — payouts arrive per Bitcoin cycle (~2 weeks), not daily.
• Reward size varies — it scales with how much STX is locked network-wide and how much BTC fees the cycle generates. Exchange stacking pools the same math; you just don’t see the details.

Stacking is optional. If you buy STX for its Bitcoin-anchored security story without wanting the lock, holding it unstacked in self-custody is perfectly fine too.
