I am not sure if you have heard of google. It is this website that lets you search the internet based on keywords.
I searched "borrow against bitcoin" and the first three non-ad results were:
https://saltlending.com/https://coinloan.io/https://lendabit.com/I have not done any kind of due diligence on any of the above companies. You will need to research any company you decide to use before entrusting them with your money.
I am also still confused why you would not just use USD, or even DAI to purchase your investment.
i googled and cant find anything
i dont want to borrow against bitcoin, i want to borrow bitcoin against usd. which isnt common
The first two platforms do not appear to offer the type of loan you are asking for, but for the amounts involved, they might try to work something out for you. I reviewed the
FAQ on lendabit and it appears they offer BTC loans secured by USDT, but if I am reading
their restrictions correctly, they will not do business with US residents.
