The main downside is complete systemic failure of the Thorchain ecosystem.

Thorchain community is confident they can offer this good deal and not fail in the long term.
I don't know if they can or not (I think it will fail in 2027).

But if they are stupid enough to offer such a good deal we should probably capitalize it before they realize their mistake. 2024 is the year to do it as 2025 is the insane bull market year where anything can happen.
