Thanks so much for the information.
From the information I saw, these firms increase their yields through a process called rehypothecation (this is a bit like money multiplier...)
e.g. by the CFO of Celsius Network
https://celsiusnetwork.medium.com/what-we-do-how-we-do-it-9a82124f7159From my understanding, US has a cap of 2x rehypothecation while UK (where Celsius and ApyHarvest are based) has no such caps (in the traditional space, not sure if cryptos fall into such restrictions) .. The UK ones claim to be doing it at 4x to 5x (which potentially suggest that they can offer higher yields on deposit than BlockFi due to regulatory differences)....
I am just curious how this actually works... does the custody partner (like Genesis) provide such services or they have to do it on their side? Most of them claim to be doing mostly collateralized lending... but why would institutional borrowers put some cryptos as collateral and borrow some other cryptos? Which cryptos are mostly used as collaterals? BTC or stablecoins such as USDT/USDC?
