Bitcoin amplification overwhelmingly drives total returns. Take a hypothetical Bitcoin treasury company, and assume Bitcoin compounds 50% a year for 4 years. Just holding Bitcoin turns $1 into $5.10. Now add amplification: senior capital (perpetual preferred equity) as a share of the Bitcoin the company holds. At 20% amplification, common equity grows 6.6x. At 60%, it grows 19.4x. Now try the other lever. Hold amplification at 40% and cut the cost of capital from 14% to 6%. Common equity goes from 9.2x to 10.3x. One lever nearly triples the outcome. The other moves it about ~13%. Across the full range, amplification explains ~98% of the variation in returns. Cost of capital explains less than 1%. Why? When Bitcoin compounds at 50%, every dollar of senior capital earns the spread between 50% and its cost. Whether that dollar costs 8% or 12% matters far less than how many dollars you have working. The catch is that amplification decays. As Bitcoin rises, the same senior capital becomes a smaller share of holdings. To hold 40% amplification in this example, the company has to grow its senior capital ~77% every year. At 60%, it has to more than double it every year. That takes deep capital access, liquidity, and investor trust, sustained through a bull market. Some important questions to ask would be what is the amplification ratio today, and can they fund it as Bitcoin compounds? Cost of capital is a detail. Amplification is the strategy:
