Is your crypto actually secure?

In this episode of the Efani Features Podcast, host Mark Kreitzman welcomes back David Wulschner, Brand Ambassador at Tangem, for a deep dive into hardware wallet security, self-custody best practices, Tangem Pay, and the latest features coming to the Tangem ecosystem.

As crypto adoption continues to grow, so do the risks. From phishing attacks and fake wallet apps to seed phrase theft and social engineering scams, protecting your digital assets has never been more important. David explains why Tangem was originally built to eliminate one of the biggest causes of crypto losses: human error around seed phrases.

Mark and David also discuss the real-world security lessons investors can learn from recent multimillion-dollar crypto thefts and why simplicity often creates stronger security than complexity.
