About 90% of Mexican household wealth sits in real estate and other physical assets, nearly the reverse of the United States.
That split wasn't built by thrift. It was built by two currency crises, a party that now controls nearly every lever of government, and a decades-long habit of trusting bricks over banks.
"Are we seeing the beginning of a new authoritarian era in Mexico, as we saw a hundred years ago? That is making people wake up... maybe there's something interesting for me here, because I can actually prepare for the risks coming with this new administration." — Gustavo Flores
Gustavo Flores Echaiz, co-founder and CEO of the Mexican Bitcoin exchange Aureo, who also writes the Bitcoin Optech newsletter, told Onramp Bitcoin Media's Final Settlement Interview Series that wealthier Mexicans are now reasoning about Bitcoin the same way.

Key Takeaways
About 90% of Mexican household wealth sits in real estate and other physical assets, Gustavo says — nearly the reverse of the United States
He traces it to the 1982 bank nationalization and the 1994 peso crisis, when the currency lost half its value overnight and deposits were frozen
Morena's judicial reform handed the party all nine Supreme Court seats and about 80% of federal judgeships, on top of a two-thirds majority in Congress
Gustavo says wealthy Mexicans increasingly see Bitcoin as a hedge against that kind of political risk, specifically because the government can't control it
Nobody in Bitcoin development is building features anymore — everyone is fixing security, Gustavo says, a shift he credits to AI-assisted vulnerability hunting
Lightning implementations have taken the worst of it; Core Lightning shipped three security releases in two weeks
Mexico's central bank has barred banks and fintechs from offering crypto directly, forcing non-financial platforms like Aureo to register as anti-money-laundering reporting entities instead
Aureo can move Bitcoin straight into any Mexican bank account in about 15 seconds, and automated buys up to $25,000 land in a wallet within a minute
1. The End Of Obscurity
Gustavo, who writes the Bitcoin Optech newsletter and co-hosts its weekly podcast, opened by describing a shift he's watched across open-source Bitcoin development over the past three to four months: almost nobody is building new features anymore.
Open-source Bitcoin development has turned almost entirely to security fixes, Gustavo says
"Nobody's working on features anymore. Everybody's simply working on security fixes." — Gustavo Flores
He attributes the shift to AI-assisted vulnerability discovery, which is hitting Lightning implementations hardest because Lightning is self-custodial but highly complex, with multiple negotiation steps. Core Lightning couldn't even publish its own source code around a recent vulnerability without exposing it, he said, and shipped three security releases in two weeks, with multiple releases from Eclair and LND alongside it. Bitcoin Core and its cryptographic primitives have fared better, mostly facing edge-case bugs rather than fund-loss risk.
The same AI-driven bug hunting is now spreading well beyond Bitcoin, Gustavo says
"If you were betting on security by obscurity, that time is over. LLMs will simply find out whatever you're trying to hide." — Gustavo Flores
He pointed to a supply-chain attack on Ledger and a cold-card hack this summer, which pushed Trezor to cancel its reseller program, and to a newly discovered flaw in how private keys are generated for general internet security systems.
