Bitcoin-Only App or Crypto Exchange: Which Suits You?

Short answer: A bitcoin-only app sells only bitcoin, usually for a fee of around 1%, and often delivers straight to your own wallet. A crypto exchange is cheaper per purchase, but holds your coins itself at first and offers hundreds of altcoins and leveraged products. For savings plans up to about €150 per purchase the app is usually cheaper and simpler; for large one-off purchases, the exchange (as of Nov 13, 2026).

You want bitcoin, not hundreds of coins

You download a crypto app to buy bitcoin. The home screen shows the "top gainers of the day", a new token up 80% and an offer of 5% interest on your coins. You find bitcoin through the search.

That is exactly the difference this article is about. A bitcoin-only app sells you a single product. A crypto exchange sells you a marketplace. Both can be right, but they are two different tools.

This article compares the two types: costs in euros and francs, where your coins sit, who supervises the provider and how the offering influences you. The individual savings plan providers with all their terms are compared in the bitcoin savings plan comparison, buying from A to Z in the guide Buying bitcoin.

What is a bitcoin-only app?

A bitcoin-only app buys and sells only bitcoin. You transfer euros or francs, the app buys for you at a fixed price and sends the bitcoin to your wallet or holds them until you withdraw.

Examples from the DACH region (Germany, Austria, Switzerland) are Relai and Pocket from Switzerland and 21bitcoin and Coinfinity from Austria. Relai, Pocket and Coinfinity deliver every purchase directly to a wallet whose keys only you hold. With 21bitcoin, the bitcoin first stay with the provider until you withdraw them.

What is a crypto exchange?

On a crypto exchange with an order book, you buy from other users. You set the price at which you want to buy (limit order), or buy immediately at the best offer (market order). Examples are Kraken and Bitvavo.

There are also crypto apps such as Bitpanda or Bison that sell to you as the counterparty themselves, but also list hundreds of coins. For this comparison they count on the exchange side: broad offering, coins held by the provider.

Bitcoin-only app vs. crypto exchange at a glance

The ranges come from the providers' fee schedules and independent comparisons (as of Nov 13, 2026, sources below). Fees change often. Check the current fee schedule before you buy.

The business model decides what you see

An exchange earns on every trade. The more often you buy, sell and switch, the more it earns. New coins, push notifications about price moves, leveraged products and rankings of the day's winners are no accident. They bring trading volume.

A bitcoin-only app earns mainly from you buying again every month. Its interest is a savings plan that runs for years. That is why altcoins, leverage and price alerts are usually missing there entirely.

For someone who wants to hold bitcoin for years, this is no detail. Most altcoins have lost against bitcoin in the long run, as Bitcoin vs. altcoins shows with the top 10 of 2017. An interface that tempts you with a new coin every day works against your plan.

Costs: when the app is cheaper and when the exchange is

The exchange advertises 0.4%, the app charges 1%. That sounds clear-cut, but it is only true without withdrawal. If you move your bitcoin to your own wallet, you also pay a fixed fee in sats at the exchange. With small amounts, this tips the comparison.

The example assumes an app with a 1% fee that delivers directly to your wallet (like Relai), and an exchange in the entry tier with 0.40% (limit order) or 0.80% (market order) and 1’500 sats per withdrawal (like Kraken).

How to measure the spread on your own purchase is shown in Bitcoin fees when buying: spread and hidden costs.

Three simple rules follow:

1. Small savings amounts: below around €160 per purchase, the app with direct delivery is cheaper, even against a limit order on the exchange.
2. Batching helps the exchange: if you only withdraw every three months, the exchange with a limit order becomes cheaper. In return, your coins sit with it for three months.
3. Large one-off purchases: with €5’000, you save around €29 or 29 francs on the exchange with a limit order.

Incidentally, the exchange's own savings plan is not automatically cheap. At Kraken, according to the comparison, a recurring purchase costs 1%, as much as the app. It only becomes cheap when you buy in the order book yourself.

How different amounts add up over the years can be worked out in the savings plan calculator. You can try it with your own amount right here:

Security: where are your bitcoin?

The bigger difference is not the fee, but where your bitcoin sit after the purchase. As long as they are with a provider, you only have a claim against it.

When FTX collapsed in November 2022, claims were valued in dollars at the price on the day of the bankruptcy, around $16’900 per bitcoin. Anyone who had 1 BTC there got dollars back, but not the price rise afterwards. The whole story is told in Exchange collapses from Mt. Gox to FTX.

An app that sends every purchase directly to your wallet has practically no such risk: after a few minutes the bitcoin are with you. With an exchange, and with apps that hold the coins themselves at first, it is up to you to withdraw regularly.

How to set up your first own wallet is shown in Setting up your first wallet: step by step. The basics of keys and seed phrase are taught in the Academy, stage 2: Understand and secure.

Regulation: both need a licence

In the EU, since July 2026 every provider that sells or holds bitcoin needs a licence under MiCA. That applies to exchanges and bitcoin-only apps alike. Relai received it from the French AMF in October 2025, 21bitcoin from the Austrian FMA in November 2025.

In Switzerland, apps such as Relai and Pocket are affiliated with a self-regulatory organisation and are thus under anti-money-laundering supervision. What MiCA means for you as a customer, and what it doesn't, is explained in MiCA and bitcoin.

A licence checks rules and capital. It doesn't guarantee that the provider will never go bust or never freeze your account. That is why withdrawing to your own wallet remains the most important protection, whichever type you use.

When a crypto exchange makes sense

The exchange is not a bad tool; you just have to use it right. It is worth it

• if you buy larger amounts in one go and place a limit order,
• if you want to sell, for example for planned partial sales, and need a fair market price,
• if you already handle wallets, addresses and withdrawals confidently.

How to use an exchange like a bitcoin-only app:

1. Buy only bitcoin. Create a watchlist with just one entry.
2. Turn off notifications. You don't need price alerts and "top movers".
3. Limit instead of market. In the entry tier, that halves the fee.
4. No leverage, no Earn. Both bring risks that have nothing to do with bitcoin.
5. Withdraw immediately. First a small test amount, then the rest to your wallet.

When a bitcoin-only app is the better choice

For most long-term holders, a bitcoin-only app is the simpler route:

• You save smaller amounts monthly or weekly.
• You want every purchase to land in your wallet without any further action.
• You don't want to wonder every time whether you are buying at the "right" moment.

Many people also use both: the app for the ongoing savings plan, the exchange for a rare large purchase or a planned sale. If you live in Switzerland, Buying bitcoin in Switzerland compares the apps and banks with their costs in francs.

Decide with three questions

1. How much do you buy each time? Under 150 euros or francs: app. Several thousand at once: exchange with a limit order.
2. Do you withdraw immediately? If not, choose an app that delivers directly to your wallet.
3. Does a large offering distract you? If you have ever bought an altcoin "just to try": app.
