P2P Arbitrage in Argentina: Crypto Dollar, Mercado Pago, PSAV and ARCA
Everything specific to P2P arbitrage with the Argentine peso: which exchanges and wallets are used, how the crypto dollar (dólar cripto) compares with the official, MEP and CCL rates since the cepo (currency controls) was lifted, what the CNV requires of virtual asset service providers from October 2026, what platforms report to ARCA (the tax agency) and how gains are taxed.
Exchanges with ARS and the current spread
The peso trades on all nine P2P exchanges P2P.Army tracks, and Binance holds about 59% of the ads. Binance joined the CNV’s PSAV registry on October 1, 2024; Bybit registered with the UIF (Financial Information Unit) on August 16, 2024, and is listed among the CNV registrants; Bitget obtained its registration on June 12, 2026. The table is live.
| Exchange | Buy USDT | Sell USDT | Spread | Ads | Activity 24H |
|---|---|---|---|---|---|
 Binance | 1,684 | 1,676 | +0.48% | 834 | 92,085 |
 Bybit | 1,687 | 1,677 | +0.59% | 236 | 15,663 |
 Okx | 1,690 | 1,675 | +0.87% | 206 | 3,633 |

 BingX | 1,820 | 1,601 | +13.73% | 79 | 8,361 |
 Kucoin | 1,717 | 1,668 | +2.93% | 28 | 41 |

Averages mix payment methods and ads from new accounts: a large or negative spread is a reason to check, not a trade. Filter counterparties by history in the order book builder.
Crypto, official, MEP and CCL dollar rates
BCRA (central bank) Communication “A” 8226 (in force since April 14, 2025) allowed individuals to buy dollars for savings without prior authorization, paying from a local account. In September 2025, “A” 8336 brought back a cross-restriction: anyone who buys on the official market cannot trade dollar-settled securities for 90 days; in April 2026, “A” 8417 extended it to those who send dollars abroad. As a result, the margin between the rates has become small:
| Rate | Pesos per dollar | Crypto dollar vs. this rate |
|---|---|---|
| Official retail (sell) | 1,560 | +5.2% |
| Wholesale | 1,539 | +6.6% |
| MEP (AL30 bond dollar) | 1,568.24 | +4.7% |
| CCL (blue-chip swap) | 1,673.87 | −1.9% |
| USDT (crypto dollar, sell) | 1,641.33 | — |
For P2P arbitrage this means the profit lies in the spread within each exchange and between payment methods, not in a large exchange-rate gap as in previous years.
Payment methods
| Method | Ads | Activity 24H | Exchanges |
|---|---|---|---|
| Mercadopago | 1,046 | 19,700 | 4 |
| Bank Transfer (Argentina) | 777 | 14,888 | 4 |
| Banco Brubank | 608 | 12,029 | 4 |
| Uala | 590 | 11,530 | 4 |
| Lemon Cash | 580 | 13,514 | 3 |
| Naranja X | 517 | 10,382 | 3 |
| Prex | 125 | 2,894 | 2 |
| Lemon | 114 | 640 | 1 |
Most trades are paid with Mercado Pago, Brubank, Ualá or other accounts via CVU or CBU (Argentine virtual and bank account numbers). Since May 2022 the BCRA has prohibited banks from trading or facilitating crypto (Communication “A” 7506), and since May 2023 it has extended the ban to payment service providers that offer payment accounts (Communication “A” 7759). On October 7, 2026, banking superintendent Juan Curutchet said that allowing crypto in banks would only be possible later on, given the current “fragility”. That is why wallets only transfer pesos: the USDT always stays on the exchange.
The paying account must belong to the same holder as the verified counterparty. Third-party payments and fake (“trucho”) Mercado Pago receipts are the most common scam: release the USDT only when the money shows up in your own app.
Taxes and regulation
| Rule | What it means for a P2P trader |
|---|---|
| Law 27,739 (Mar 15, 2024) | Creates the category of virtual asset service provider (PSAV) within the anti-money-laundering regime; the CNV keeps the registry |
| CNV General Resolution (RG) 1058/2025 | Registration deadlines in 2025 and obligations enforceable from Dec 31, 2025; excludes trading on your own account |
| CNV RG 1172/2026 (in force since Oct 16, 2026) | Replaces the PSAV regime. Individuals register only if their activity on behalf of third parties exceeds 35,000 UVA per month (with an accountant’s certification). Exchanging crypto on your own account, at any amount, is excluded. Bans mixers; new monthly report PSAV_014 from Nov 1, 2026 |
| P2P merchants | RG 1172 does not mention P2P. It is unresolved whether a regular P2P merchant acts “on behalf of third parties” |
| ARCA, RG 5804/2025 | Platforms and wallets report users’ balances and movements above ARS 50 million per month (individuals) or ARS 30 million (companies), starting with the May 2026 filings |
| Income tax (Ganancias) | By law: 5% for sales in pesos without an adjustment clause and 15% in foreign currency or with adjustment; foreign-source gains, 15%. In practice, interpretations differ |
| Personal assets tax (Bienes Personales) | Crypto holdings are subject to this tax (ARCA) |
| Law 27,799 “Fiscal Innocence” (Official Gazette, Jan 2, 2026) | An optional simplified income tax return for individuals with income of up to ARS 1 billion and assets of up to ARS 10 billion; the tax evasion threshold rises to ARS 100 million |
| CARF | On Sep 14, 2026, Argentina committed to the international exchange of crypto information; first exchanges by September 2029 at the latest |
If you trade P2P frequently and in volume, consult an accountant on two points: whether the CNV could consider your activity to be on behalf of third parties, and which income tax rate applies to your trades.

Local risks
The best-documented risk is fake receipts (comprobantes truchos) and cloned Mercado Pago apps: the buyer shows a screenshot of a transfer that never arrived. The second is getting paid from a third party’s account: if that money comes from a scam, the victim’s claim lands on your account. In addition, with ARCA reporting and the PSAV registry, a high volume of P2P trades without accounting records becomes visible.
- Trade with counterparties who have more than 100 orders and a 95%+ completion rate; for large amounts, verified merchants only.
- Accept money only from the holder of the verified (KYC) account — never from third parties, relatives or “company accounts”.
- Confirm the credit in your own bank or wallet app, not from a screenshot or an SMS.
- Use a separate account for P2P and withdraw profit regularly.
- For every trade, save the order number, chat, account statement, transfer receipt and the counterparty’s KYC name.
- Do not accept receipts sent over WhatsApp as proof: verify the credit in the app.
- If your volume grows, keep a trade log ready for your accountant and for ARCA.

Frequently asked questions
Is P2P crypto trading legal in Argentina?
Yes. The CNV regulates virtual asset service providers; trading on your own account requires no registration. Under RG 1172/2026, an individual registers if their activity on behalf of third parties exceeds 35,000 UVA per month. This is educational material, not legal advice.
How much income tax (Ganancias) applies to selling crypto?
By law, 5% for sales in pesos without an adjustment clause and 15% in foreign currency or with adjustment; foreign-source gains, 15%. In practice, interpretations differ: consult an accountant.
Do exchanges report my trades to ARCA?
Yes, above ARS 50 million per month in inflows, outflows or balance (individuals), under RG 5804/2025, starting with the May 2026 filings.
Is there a gap between the crypto dollar and the official rate?
A small one: on October 29–30, 2026, USDT traded about 5% above the official retail rate and the MEP, and 2% below the CCL.
Can I buy crypto directly in Mercado Pago or at my bank?
The BCRA prohibits banks and payment service providers with payment accounts from trading or facilitating crypto (Communications “A” 7506 and 7759). Wallets are used to transfer pesos; the USDT stays on the exchange.
