In this episode of Proof of Pain, Tony sits down with Nik Lentz, former UFC veteran and quantitative analyst, to talk about Bitcoin, MSTR, STRC, and the risks around digital credit. We also get into Nik’s path from MMA to finance, how he learned to think like a quant, and why he has become skeptical of Wall Street’s version of Bitcoin.

Nik is not anti-Bitcoin. He makes the case that Bitcoin wrappers, yield products, and “easy” digital credit stories are being sold too cleanly, that “11%” narratives do not hold up forever, and that if you really believe in Bitcoin, you should just buy Bitcoin. We also cover MSTR volatility, ETF wrappers, risk vs reward, and how faith changed the way he sees pain, markets, and life.

What we cover• Nik’s path from childhood adversity to wrestling, UFC, and eventually finance• Why the transition from fighting to quant/trading made more sense than people think• Nik’s early Bitcoin experience and why he was interested so early• Why he is skeptical of ETF wrappers and Wall Street Bitcoin• MSTR, STRC, SATA, and the broader digital credit / yield story• Why Nik says “11% is make believe” and rejects the idea of a free lunch• Why he thinks volatility is the price of outsized returns• Faith, pain, risk, and how his worldview changed over time

In this episode of Proof of Pain, Tony sits down with Jim Crider, certified financial planner and founder of Intentional Living FP. They talk about what money is, why so many people in finance still misunderstand Bitcoin, and how Jim thinks about portfolio construction in a world shaped by inflation, money printing, AI, and rising uncertainty.

They also cover Jim’s path into financial planning, how Bitcoin finally clicked for him during the COVID era, whether the 60/40 portfolio is broken, how he thinks about cash, bonds, stocks, real estate, and gold, and why most investors need to think more clearly about risk, time horizon, and allocation. The conversation also gets into Bitcoin treasury companies, STRC and SATA, black swan scenarios, stewardship, faith, and truth-seeking.

In this episode of Proof of Pain, Tony sits down with Mike Flaum (Grain of Salt) to break down Bitcoin investing through a product manager lens: optionality, taxes, IRAs, and why “shares per Bitcoin” can be the clearest way to understand Bitcoin treasury companies like Strategy (MSTR).

What we cover• Product manager investing: TAM, tradeoffs, first principles• Paying taxes vs never taking profit• Bitcoin in IRAs, wrappers, and buckets• Strategy (MSTR): converts vs preferreds vs cash• Shares per Bitcoin vs Bitcoin per Share (pizza analogy)• AI deep research workflows (ChatGPT, Claude, Grok)• Why mNAV can mislead, and the metric Mike wants standardized
