Meet Open Wallet, a Self-Custodial Alternative to Bitso

Bitso is one of Latin America's most trusted exchanges. But trusting Bitso with your crypto and owning your crypto are two very different things. Open Wallet gives you everything Bitso does — trading, swapping, stablecoin yield, even perpetuals — while you stay in full control of your assets.

Bitso vs Open Wallet: Quick Comparison

What Is Bitso?

Bitso is a centralized crypto exchange founded in Mexico in 2014. It is one of the most established names in Latin American crypto, with operations across Mexico, Brazil, Argentina, and Colombia, a clean security record since launch, and regulatory licenses across its core markets.

Its main product is a centralized exchange with direct bank integrations via SPEI in Mexico and PIX in Brazil. For Mexican and Brazilian users who want a regulated, reliable way into crypto, Bitso has earned its reputation.

It also offers Bitso Earnings, an opt-in yield feature paying around 4% APY on USDC and USDT, and supports 100+ assets across 20+ networks including perpetuals.

What Is Open Wallet?

Open Wallet is a self-custodial crypto wallet. Mexican and Brazilian users get everything they can do on Bitso, while keeping full cryptographic ownership of their assets throughout.

The off-ramp works the same way: USDC converts to MXN via SPEI or BRL via PIX and lands in your bank account in under two minutes, no P2P involved. For trading, a built-in DEX covers spot swaps across chains. For perpetuals, Jupiter on Solana is a tap away. There is nothing you can do on Bitso that you cannot do with Open Wallet.

The difference is what happens to your crypto in between. On Bitso, it sits on their servers. On Open Wallet, it never leaves your hands.

Recovery does not require a seed phrase. MPC (multi-party computation) technology splits your key across secure environments. Lose your device, and full wallet access is back in around 60 seconds.

Where Bitso Falls Short

1. You Don't Own Your Crypto

Bitso is fully custodial. Your private keys live on Bitso's servers, not on your device. In the blockchain sense, you do not hold your crypto. You hold a claim against Bitso's balance sheet.

This only becomes visible when something goes wrong. Paxful, one of the largest P2P platforms in Latin America and Africa, shut down in November 2025. Users who held funds on the platform spent weeks navigating a recovery process. The same thing happened when OKX exited Nigeria in August 2024, and when exchanges froze withdrawals during the 2022 bear market. Bitso has had none of these issues — but the architecture that would cause them is identical.

With a self-custodial wallet, a platform going offline is an inconvenience. With a custodial one, it is a crisis.

2. Stablecoin Yield That Could Be Regulated Away

Bitso Earnings currently pays around 4% APY on USDC. That is a real benefit, but it comes with a structural risk that is easy to miss.

Bitso is a regulated, centralized financial institution. The yield it pays on stablecoins is, in regulatory terms, close to a savings account. Banking federations in Mexico and Brazil are already watching stablecoin yield products closely, because they compete directly with traditional savings. Regulatory pressure that cuts or removes this feature from centralized platforms is a growing risk.

DeFi protocols like Morpho work differently. They are permissionless infrastructure. No central entity that regulators can compel to change rates, restrict access, or shut down a yield product. Open Wallet's Morpho integration (coming soon) will offer 5-7% APY on USDC, and that yield is structurally protected in a way that Bitso's is not.

3. Withdrawal Fees That Add Up

Bitso's TRC-20 USDT withdrawal fee is 12.14 USDT. On most platforms, TRC-20 is the cheapest network for USDT transfers — fees of $0.50 to $2 are standard across the industry. Bitso's fee is among the highest in the market for this specific operation. Most users choose TRC-20 precisely because they expect it to be cheap. On Bitso, it is not.

For anyone regularly moving USDT out of Bitso to an external wallet or DeFi protocol, this fee adds up fast.

Where Open Wallet Has the Edge

Self-Custody: You Always Control Your Keys

Open Wallet uses MPC architecture. Your private key is never stored in a single location and never held by any third party. Key shards are split across your device and secure computation environments. Open Wallet cannot access your funds, cannot be forced to freeze them, and a breach of Open Wallet's servers does not touch your assets.

Your crypto behaves like cash in your hand, not a balance in someone else's ledger.

Off-Ramp: MXN and BRL in Under 2 Minutes

USDC goes to your off-ramp address. Pesos or reais land in your Mexican or Brazilian bank account in under two minutes, via SPEI or PIX. No P2P, no counterparty, no waiting. The same speed you get from Bitso, with the same direct banking rails, and full self-custody throughout.

Everything Bitso Does, Without Giving Up Your Keys

Spot trading, token swaps, stablecoin holds, cross-chain transfers — all available inside Open Wallet through an integrated DEX. For perpetuals, Jupiter on Solana is directly accessible. There is no trade-off on functionality. You are not giving anything up by moving to self-custody.

Recovery Without a Seed Phrase

Traditional self-custodial wallets require a 12-24 word seed phrase. Lose it, and everything is gone permanently. Open Wallet removes this through keyless MPC recovery: lose your device, verify your identity, and full wallet access is back in around 60 seconds. Self-custody without the single point of failure.

Stablecoin Yield That Stays Yours

Open Wallet's Morpho integration (coming soon) will offer 5-7% APY on USDC held in your self-custodial wallet. No minimums, no lock-up periods. And because Morpho is a permissionless DeFi protocol, the yield is not subject to the same regulatory pressure building around centralized platforms that offer savings-like products. When banking regulators turn their attention to stablecoin yields on exchanges, DeFi protocols sit outside that perimeter.

Who Should Use Bitso?

Bitso is a good exchange for specific users. If you are new to crypto and want a simple, regulated, beginner-friendly way to buy and sell with direct bank integration in Mexico or Brazil, Bitso does that well. Its track record, regulatory standing, and straightforward interface make it one of the better centralized exchanges in the region.

If you do not yet care about self-custody, are not moving significant volume, and want the simplest possible experience, Bitso is a reasonable choice.

Who Should Use Open Wallet?

Open Wallet is for the user who understands that "your exchange holds your crypto" and "you hold your crypto" are not the same thing, and has decided the difference matters.

It is the right fit for traders and investors in Mexico and Brazil who want the same off-ramp speed and trading functionality as Bitso, without the custodial risk. For anyone who has watched what happens when platforms freeze withdrawals and decided they do not want to be in that position. For users who want stablecoin yield that is structurally protected from the regulatory pressure building around centralized savings products.

Everything Bitso offers. Your keys. Your coins.

Bottom Line

Bitso and Open Wallet offer the same core functionality: spot trading, token swaps, perpetuals, stablecoin yield, and direct off-ramps to MXN and BRL. The difference is not what you can do. It is who holds your assets while you do it.

Bitso holds your crypto. Open Wallet does not.

If Bitso's infrastructure ever faces a regulatory action, a technical issue, or an event that pauses withdrawals, your access to your funds depends entirely on their ability to resolve it. With Open Wallet, that scenario does not apply. Your crypto is yours, cryptographically, at all times.
