Ask HN: What should I do with Blockfi holding my BTC collateral against my loan?

I've got significant amount of money as BTC collateral at Blockfi.

I've heared that Blockfi maybe treats deposits chasing yields as loans, which I understand (and I understood the difference when I was taking out loan against my BTC collateral).

I'd like to repay my USD loan and get back my BTC collateral, as I made a mistake of trusting the company keeping funds separate.

I understand that I'll probably not see that money again, but my question is whether I should get a lawyer (and what kind of lawyer), or just wait to see what happens?
