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.
