Description

In this episode, I sit down with Wojciech Kaszycki — serial entrepreneur, business angel behind 19+ ventures, and the mind behind both Mobilium and BTCS.Wojciech shares how he went from building one of Poland’s earliest e‑commerce platforms to pioneering fintech and crypto infrastructure. We explore why his teams focus on building real, regulated bridges between traditional finance and digital assets — not just hype.We dig into how Mobilium plans to let you use Bitcoin as collateral to spend or borrow against, and how BTCS builds a treasury + validator network to bring yield and Web3 services to a wider audience.He also gives practical advice for founders and investors: why a crowded “yes” may be a warning sign — and why sometimes it's the weird, rejected ideas that deserve to be built.If you care about honest, long-term crypto infrastructure and what it takes to build it — this one’s for you.It would mean a lot if you can leave a review of this podcast on Apple Podcasts or Spotify — and share this podcast with a friend.

Lack of skepticism could mean low barriers to entry and limited upside. 00:03:00My path: from building Poland’s “Amazon‑like” e‑commerce to fintech and eventually entering crypto — bridging traditional finance with digital assets. 00:06:00With Mobilium, we don’t just offer a crypto card — we hold real lending licenses so users can borrow against their Bitcoin without selling it. 00:11:00Mobilium’s revenue comes from service fees on on‑ramps/off‑ramps, interchange fees from cards, and interest on crypto‑collateral loans. 00:13:00When building products — don’t just build what you think is best. Test with real users. But beware: too many opinions can derail focus. 00:18:00BTCS combines a crypto treasury, staking/validator infrastructure, and smart yield strategies — aiming to grow with the value of crypto, not just fiat. 00:22:00Key metrics for BTCS: monthly reward ratio (yield vs net asset value) and compound growth of net asset value per share. 00:28:00Sometimes you’re just early — don’t be afraid to fail. If your vision holds, the market may catch up later.Connecthttps://www.mobilum.com/enhttps://x.com/Mobilumofficialhttps://x.com/wkaszyckihttps://www.linkedin.com/company/mobilumcom/https://www.linkedin.com/in/wojciechkaszycki/DisclaimerNothing mentioned in this podcast is investment advice.
