Let's say I have $100k in stables, but I would like to borrow more so that I have $500k - $1m. I understand it can't be withdrawn from the protocol, but is there a place to do this? It is possible on CEXes as margin trading on spot. In other words borrow stables onchain with looping. Eg. to buy more ETH, ideally with a fixed borrow rate. And please before someone mention that I can use AAVE and deposit ETH as collateral and borrow 85% of initial, this is not the same.(Route 2 FI)
