No, it's not. This is a high risk loan. Limited upside, unlimited downside.
Downside is limited to your principal investment.
You can't be busted to below zero, unless you borrowed to make the investment.
You’re right, the upside is fixed at 17% and my comment wasn’t really addressing the contents of yours, but the general sense of unease I get talking to people about their “crypto positions” as if having some > 1% (often a lot more) portion of their whole net worth “in crypto” is a reasonable part of a balanced portfolio.
