The current financial and education systems aren’t just broken, they’re failing the next generation.

In this episode of Trezor Talks, Sean sits down with Lina Seiche, creator of The Little HODLer, to explore why financial education matters, how inflation has been normalized, and why people should understand money before they’re encouraged to take on debt.

Lina shares her journey from musician to Bitcoin educator, how The Little HODLer grew into a global project, and what it’s really like working with the Ministry of Education in El Salvador to teach kids about value, savings, and ownership.

In this conversation, you’ll learn:

• Why “financial freedom” means control, not wealth

• How inflation has been quietly normalized

• Why we don’t teach kids about money (and what it costs us)

They made the first-ever auditable Secure Element chip. This changes everything for crypto security and beyond…

Jan Pleskač (CTO) and Kryštof Jelínek (CBO) have been part of Tropic Square’s 5+ year mission to solve the problem of closed architecture chips that have NDAs and limited transparency. 

Imagine this: your device has a Secure Element chip to protect your secrets, but when a flaw is found, you’re not allowed to disclose it!

That’s the reality for many closed chips today. Tropic Square is changing that with community-verified chips, so you don’t have to trust blindly.  

In this podcast, you will discover:

• Why open-source transparency is vital for future-proof crypto security

• How auditable chips protect against hidden vulnerabilities

• What open architecture hardware means for trust and innovation

• How Tropic Square approaches the quantum threat

  
  

And more insights from 5+ years of development.
