Repay a loan with mining income

A monthly routine: payouts arrive in BTC, you convert the share you need to the loan currency, repay, and track what is left.

Intermediate

A loan against bitcoin is easier to carry when something pays it down every month. Your machines can be that something. Payouts arrive in BTC, the loan is in dollars or a dollar token such as USDC, and a simple monthly routine connects the two.

Careful: Borrowing against bitcoin can lose the collateral. Mining income is not guaranteed: it depends on bitcoin's price, network difficulty and uptime. A repayment plan built on mining needs a fallback. This guide is education, not advice.

Before you start

The monthly routine

  1. Pick a date. The same day every month, after your hosting invoice is settled.
  2. Read the month. Open Earnings and note what was mined and paid out.
  3. Decide the share. Choose in advance what part of the month's mining goes to the loan, or a fixed dollar amount. Keeping to the rule matters more than the exact number.
  4. Convert only that share. Sell that amount of BTC for the loan's currency at an exchange. For an on-chain loan, withdraw the dollar tokens to the wallet that holds the position, on the right network. See Cash out overview.
  5. Repay. With a custodial lender, pay the way the lender instructs. On Aave, use Repay under Your borrows, or the portal's Borrow page when the feature is on for your account.
  6. Check the result. Look at the new balance and the new health factor or LTV.
  7. Write it down. Date, BTC sold, price, amount repaid, balance left.

Good to know: The rest of the month's bitcoin stays yours to keep. The routine sells only what the plan calls for.

Track it

A simple sheet is enough. It shows the loan shrinking, and it gives you the records you will want at tax time. Selling BTC to repay a loan may be a taxable event where you live: see Tax records for mined bitcoin and ask a tax professional.

Interest first

If your repayment is smaller than the interest added that month, the loan grows. As a minimum, aim to cover the interest, then reduce the amount borrowed with whatever is above it. With a variable rate, check the current rate each month: it may not be what it was when you borrowed.

When mining income dips

Mining income moves. A lower bitcoin price, a rise in network difficulty, a halving or a machine offline for repair all reduce a month's payouts. A lower price hurts twice: the mining buys fewer dollars, and the collateral is worth less at the same time.

Automating the watch

Firsthand's auto-loan rules can propose the monthly repayment for you, sized as the share of mining income you set, for your wallet to sign. The feature is being rolled out and may be off for your account. See Auto-loan explained.
