I guess there are services like Unchained or LEDN, or you can do P2P lending
You can do it P2P on hodlhodl, and you're looking at 15-42% APR and finding orders based on your size is a pain in the arse, but you do the math and decide on the exposure along with the fees involved in moving on-chain and then the cost to acquire stables again to pay off your loan
Also keeping aside capital if LTV dips, its a ballache
It's not easy street thats for sure, and honestly most people shouldn't be using leverage lol
What happens when btc dips?
The lender takes that percentage back?
You woild probably be getting a fraction of the worth and taking all the risk.
Leaves a bad taste in my mouth.
