Are these things full recourse? Because while a doubling sounds quite nice, you would need to earn 25% from the current state of 800M to break even on that additional collateral of 200M. Sounds strictly worse than just liquidating the original loan to achieve net zero and then doing a different loan with your 200M of extra assets.
If you can liquidate 800M to rid yourself of a 1B loan then it seems fairly obvious to do it?
You're liquidating the 800M and still owe your broker 200M, it's risk avoidance not a church full of forgiveness.
Many people don't bother looking for alternatives because it is shipped by default in their web browser. They may don't even know what a search engine is, nor that there are more than the one they use on a daily basis, but have internalized "google" as a verb.
I for example "still" use it. Sometimes it still gives more precise results than any other alternative. No alternative I've ever tried gives precise local results for this country - DuckDuckGo or Mojeek, for example, not only don't have "Colombia" in it - they don't have anything "Latin America" in it.
And I don't want to spend money on something like Kagi. Not even sure if they accept payments from here, and not a fan of the idea of even more paid subscriptions.
