The cheapest and most common route is to fund a CNBV-authorized platform — Bitso (via NVIO Pagos México) or Binance (via Medá) — with a free SPEI bank transfer and buy on the MXN order book, where Bitso’s commission starts at 0.60% maker / 0.78% taker and falls as 30-day volume rises. The tax fact a buyer must know: gains are taxed as ordinary income at a progressive 1.92%–35% for individuals, crypto-to-crypto swaps count as taxable disposals, and only the first 3 annual UMAs of gain (MXN 128,383.92 in 2026) are exempt.
Legal status
Legal to buy, hold and sell — not legal tender. Defined as an “activo virtual” under the 2018 Ley Fintech; Banxico Circular 4/2019 bars banks and fintechs from offering crypto to the public.
Exchanges you can use
| Exchange | Type | License | Notes |
|---|---|---|---|
| Bitso | regional | IFPE via NVIO Pagos México (CNBV) + Gibraltar DLT licence | dominant; free SPEI deposits/withdrawals |
| Binance (Medá) | major | IFPE via Medá (CNBV, 2022; launched Sept 2025) | direct MXN via SPEI |
| Banxa | regional | payment infrastructure (no Mexican licence) | buy-only SPEI ramp |
KYC requirements
INE/IFE + CURP + RFC + proof of address + selfie
CURP validated against RENAPO; limits scale with verification level.
Payment rails
- SPEI — free (Bitso); 0.5% (Kraken) · real-time interbank, 24/7 — the default on/off-ramp
- OXXO cash — premium vs SPEI · cash funding for the unbanked (Banxa)
Stablecoins — which one works here
- USDT: Dominant for P2P and remittance settlement (mostly TRON)
- USDC: Strong in the US–Mexico corridor (Circle-settled, e.g. Felix Pago)
USDC + USDT were 40% of Bitso retail purchases in 2025 — first time stablecoins beat BTC (18%).
Tax
No crypto-specific tax — gains taxed as ordinary income (enajenación de bienes): progressive 1.92%–35% individuals, flat 30% companies
Exemption on the first 3 annual UMAs of gain (MXN 128,383.92 in 2026). Crypto-to-crypto swaps are taxable disposals.
Bank account risk
Banks/fintechs barred by Circular 4/2019 from offering crypto; crypto balances have no IPAB insurance; CONDUSEF states users cannot formally claim for crypto fraud.

FAQ
Is crypto legal in Mexico in 2026?
Yes. Buying, holding and selling is legal, but it is not legal tender and banks/licensed fintechs may not offer it to the public under Banxico Circular 4/2019.
How much tax do I pay on crypto gains in Mexico?
Gains are taxed as ordinary income — progressive 1.92%–35% for individuals (flat 30% for companies), with an exemption on the first 3 annual UMAs of gain (MXN 128,383.92 in 2026).
What ID do I need to open a crypto account in Mexico?
A government photo ID (INE/IFE or passport), CURP, RFC, proof of address and a selfie.
Can a Mexican bank sell me Bitcoin?
No. Banxico Circular 4/2019 bars credit institutions and fintechs from offering crypto exchange, custody or transfer to the public.
What is the cheapest way to buy crypto with MXN?
Fund with a SPEI bank transfer: Bitso charges no fee on MXN deposits or withdrawals, so the only real cost is the trading commission, which starts at 0.60% maker / 0.78% taker on MXN markets for users below 20,000 MXN of 30-day volume and drops through nine tiers as volume grows. Card and cash (OXXO) top-ups cost more than SPEI, and on any rail the executed price also carries a spread.
Can I use crypto to send money between the US and Mexico instead of a remittance service?
Yes. Banxico recorded USD 61,791 million in remittances to Mexico in 2025, and the World Bank put the average cost of sending money US→Mexico at 4.54% in Q3 2025 — Mexico being the cheapest receiving market in the G20 — while a USDT or USDC transfer settles on-chain for cents and the recipient can cash out to a CLABE via SPEI on a regulated platform. Bitso reports it processed USD 6,500 million of that corridor in 2024, over 10% of the total.
Should I move my crypto into my own wallet, and which network should I use?
Bitso’s withdrawal fees differ sharply by network for the same asset — USDT costs 3.5 USDT on Tron versus 0.01 USDT on Polygon, and BTC is free over Lightning versus 0.00001543 BTC on the Bitcoin network — so send on the cheapest network your destination wallet supports. Self-custody matters more than the fee for sizeable balances, because exchange holdings carry no IPAB deposit insurance and CONDUSEF does not let users formally claim for crypto fraud.
