The lesser of (Token balance, (BTC balance - 0.000402832) * BTC price denominated in the token according to the given AMM pool)
Default max borrow with BTC collateral:
The lesser of (available liquidity in the lending pool, ((((BTC balance - 0.000402832) * (1 - Origination fee rate)) * BTC price in the loan asset) * Maximum initial loan-to-value ratio) - Prepaid interest amount)

Prepaid interest amount formula:
(maxBorrow / (1 - interestRateForDuration)) - maxBorrow
maxBorrow is ((((BTC balance - 0.000402832) * (1 - Origination fee rate)) * BTC price denominated in the loan asset) * Maximum initial loan-to-value ratio)
interestRateForDuration is (Borrow APR * (60 * 60 * 24 * Prepaid interest duration) / 31536000)
Putting it all together:
((((BTC balance - 0.000402832) * (1 - Origination fee rate)) * BTC price denominated in the loan asset) * Maximum initial loan-to-value ratio) / (1 - (Borrow APR * (60 * 60 * 24 * Prepaid interest duration) / 31536000)) - ((((BTC balance - 0.000402832) * (1 - Origination fee rate)) * BTC price in the loan asset) * Maximum initial loan-to-value ratio)
