I would try to reframe: Lets say you think you can get 5% on a "low"risk investment leveraging your Bitcoin stack. Well there must be some risk, are you sure its low? Are you sure you can quantify it accurately? For now, lets just blindly assume you can. That 5% is still a fiat lie. You are doing that 5% math based on something like this: I have $1,000 worth of BTC and think I can make $50 per year, so 5%. But that is incorrect. That $1,000 worth of Bitcoin could be worth $10,000 in a few years. So lets redo the math: $50 / $10,000 = 0.5% (0.005) How do you judge that "low" risk investment now that you realize the bitcoin adjusted return is not 5% per year, its really 0.5%? Is it really worth risking your stack for a 0.5% return? Your return is much lower than you realize and your risk is much higher than you realize if you can accept how much higher BTC can go. If you owned real estate in Manhattan in 1920 would it be a smart play to leverage it up when the Great Depression could be around the corner? No but you're so caught up in the roaring 20s that you think they'll go on forever.

*yes I am oversimplifying and not thinking about rate vs APY or compounding etc. but you get the point - this is for illustrative purposes not perfect math
