How to buy bitcoin in Argentina with Lemon

What you will end up with

Bitcoin bought with pesos, sitting in a wallet whose recovery phrase you wrote down yourself, with the exchange out of the picture. Not a balance on Lemon's screen: coins you can move without asking anyone.

The distinction is the whole point of this guide. Buying is the easy half and the part every exchange makes frictionless. The half that matters is the withdrawal, and it is the one people put off for years.

Who this is not for. If you already run a wallet and want to buy without a custodian in the middle, this is the wrong route and a peer-to-peer trade is the right one. This guide is for someone in Argentina with no bitcoin at all, holding pesos that lose value while they think about it.

Before you start

• An Argentine DNI and CUIL or CUIT. Lemon runs identity checks, which means the purchase is not private and is reported. That is a feature of every regulated exchange in the country, not something specific to Lemon.
• A bank account or a Mercado Pago balance in your own name, to fund the account.
• A destination wallet, set up and backed up before you buy anything. BlueWallet is the simplest place to start for on-chain use. Phoenix and Muun are self-custodial and handle Lightning, at the cost of more moving parts to understand. Set the wallet up first, because a guide that has you buy and then figure out custody is how balances sit on an exchange for three years.
• The exchange's registration, checked yourself. Argentina's Comisión Nacional de Valores keeps a public register of virtual asset service providers. Look up any platform you are about to hand pesos to, including this one. It tells you who is accountable to whom, and nothing more than that.

We have no relationship with Lemon, are paid nothing by them, and use no affiliate links. The alternatives are real ones: Belo, Ripio, and Buenbit, which Nexo acquired in December 2025 and now operates as Buenbit by Nexo. The steps below are Lemon's because that is the app this post covers; the shape of them is the same everywhere.

The tradeoff you are accepting

While the bitcoin sits on Lemon, you do not have it. Lemon holds the keys, and what you have is an entry in their database saying they owe you. That arrangement works right up until it does not, and the failures are not hypothetical: FTX showed exactly what a balance on a screen is worth when the company behind the screen is insolvent.

Withdrawing fixes that and creates a different exposure. Once the coins are in your wallet, a lost recovery phrase is a permanent loss with nobody to appeal to, and a mistyped withdrawal address sends the money to a stranger. You are trading counterparty risk for your own carefulness. Take the trade, but take it with your eyes open, and read what self-custody actually costs before the amount gets large.

Steps

Checked against the Lemon app and its public help centre in August 2026. Interfaces move; if a button below is not where this says, the help centre is the current source and this post is not.

1. Install the Lemon app from the App Store or Google Play, or open lemon.me. Check the developer name before installing: cloned wallet apps are the most common way people in Argentina lose a first purchase.
2. Create the account with your own details and complete the identity check.
3. Turn on two-factor authentication before you deposit anything. This is a custodial account with a login, so account security is genuinely your problem here, in a way it will not be once the coins are in your own wallet.
4. Fund the account in pesos by bank transfer or from Mercado Pago.
5. Buy bitcoin. Do the first purchase small, at an amount you would not mind losing to your own mistake.
6. Before withdrawing anything, look at the total cost. Compare the price you were shown against a public reference rate at that moment, and add the withdrawal fee. The spread is usually larger than the fee, and it is the number nobody quotes.
7. Open your own wallet and copy a receive address from it. On-chain Bitcoin addresses start bc1, 3 or 1. A Lightning invoice starts lnbc.
8. In Lemon, start a BTC withdrawal and select the network that matches the address you copied. Lemon supports both on-chain Bitcoin and Lightning; sending on the wrong network is how funds are lost, and the help centre says so plainly in its note on choosing a withdrawal network.
9. Send a deliberately small test amount first. Wait for it to arrive.
10. Only after the test arrives, withdraw the rest.

Verify it worked

1. Check your own wallet shows the balance, not Lemon's confirmation screen. Lemon telling you it sent is a claim about their side.
2. Look the transaction up on a block explorer using the transaction ID from Lemon. The coins are yours when the transaction is confirmed in a block and the receiving address is the one from your wallet.
3. Spend a small amount back out of your wallet to somewhere else you control. This is the step almost everyone skips, and it is the only one that proves you can actually move the money rather than merely see it.
4. Restore your wallet from its recovery phrase on a second device, before the balance gets meaningful, and confirm the same first address appears. A backup you have never restored is a backup you are guessing about.

If something goes wrong

The withdrawal is pending for hours. On-chain, check the transaction ID on a block explorer: if it is in the mempool, it is broadcast and the fee is the only question. If Lemon has not given you a transaction ID at all, it has not been broadcast, and that is a support question rather than a network question.

You sent to the wrong network. A Lightning invoice pasted into an on-chain withdrawal will usually be rejected as malformed, which is the good case. Anything that does go out and lands somewhere you do not control is gone. This is why step 9 exists.

The test amount never arrived. Stop. Do not send the rest to prove a point. Check the address you copied character by character against the one in the withdrawal, and check that you copied from your wallet's receive screen rather than from a message or a screenshot.

Your account is frozen for a compliance review. This is the ordinary behaviour of a regulated custodian and it can take days. It is also a good illustration of what "your balance" means while it is still on the exchange.

You lost the recovery phrase for your own wallet. If the coins are still on the exchange, nothing is lost, so write it down now. If they have already been withdrawn, there is no recovery path. Nobody has a copy, by design.

That asymmetry is the honest summary of this whole procedure. The exchange can freeze you and can fail; your own wallet can do neither, and will also never help you.

Update, 20 August 2026. Buenbit, listed here as an alternative, was acquired by Nexo in December 2025 and now trades as Buenbit by Nexo. The withdrawal section has been rewritten around Lemon's current on-chain and Lightning support, and the earlier version's closing material was removed.
