Hi, you also have the option of summer.fi
(previously known as oasis) loans albeit it uses wbtc as collateral
for bitcoin (which is not the same as native bitcoin) with aprox 5.5% borrow rate.
With native bitcoin you could use thorchain,
it has no interest rate, but it only allows 33% LTV with a 'novel' mechanism which for my taste it has a luna-esque flavour.
see for example

and with some caveats(*)
With eth you could instead use wstETH wrapped lido staked
eth as collateral which compounds at around 3.7% so for example a loan in summer.fi would result in a 1.3% interest. Aave allows to use stETH also as collateral (weird they dont use wstETH instead, as rebase tokens have funny tax implications).
(*) there is another potential issue, as its the only defi protocol
that currently allows switching from ETH land to native Bitcoin and viceversa, by passing KYC, and thus when you reverse the situation you could get 'tainted' btc.
Hope it helps.
Disclaimer:
Of course it is not the same to hold ETH instead of stETH (or wstETH)
albeit at present the market values that risk at 0%.
And wbtc instead of BTC (with a similar 1:1 peg).
IOU pegs work untill they don't
