El Salvador, which made Bitcoin legal tender last September, is at risk of a multibillion-dollar national default after pumping hundreds of millions of dollars into Bitcoin before the currency’s price collapsed.

Twitter also lets users from the US (except Hawaii and New York) and El Salvador tip fellow tweeters with Bitcoin. Twitter’s Tip Jar lets users send fiat money and Bitcoin via third-party payment services like PayPal and Cash App. Big Tech competes for crypto crown: Twitter, Amazon, Google, and Meta have all dipped their toes in the water as they look to expand into crypto.

US-based Intermex plays a large role in the Latin American remittance space: In Q1 2021, Intermex had a 19.6% share of its four core markets of Mexico, Guatemala, El Salvador, and Honduras—up from 19.4% in 2020. US-based Ria has also been ramping up its expansion in Mexico.

The news: Twitter users from the US (except Hawaii and New York) and El Salvador can now tip fellow tweeters with Bitcoin, per Finextra. Here’s how it works: First launched in May, Twitter’s Tip Jar lets users send fiat money and now also Bitcoin via third-party payment services, like PayPal, Cash App, Venmo, and more.

Globally, El Salvadorian President Nayib Bukele recently announced plans to adopt Bitcoin as a legal tender, which would make El Salvador the first country to do so. And in some parts of Switzerland, residents can use Bitcoin for public services like tax payments.

What we’ve noticed: As the crypto payments market gains steam, lawmakers and regulators across the globe are trying to figure out how to regulate digital currencies effectively to ensure safety and legitimacy—a debate that took on a new sense of urgency after El Salvador became the first country to accept Bitcoin as legal tender.
