Example

Your BTC balance is 1,000,000 sats and BTCUSD bid-offer is: 19,995 - 20,005 USD.

If you convert your BTC balance to synthetic USD, you will get:

1,000,000 × 19,995 / 100,000,000 = 199.95 USD

If you convert back to BTC when BTCUSD is 20,000 USD:

199.95 × 100,000,000 / 20,000 = 999,750 sats
