What's the catch?

Every credit product is a trade. This one is stated plainly enough that you can decide against it.

You are exchanging some future upside for capital today.

What you keep

All appreciation up to the call strike. Every dollar of gain below that level is yours.

$50,000 per BTC at 0% interest. No rate, no accrual, no monthly servicing, no payment schedule.

Downside protection below the put strike. Your loss stops tracking Bitcoin all the way down.

Fixed terms. Strikes, LTV, term and repayment amount are set at the start and cannot be changed by anyone.

What you give up

Gains above the call strike. This is what funds the financing. It is the real cost of the 0%, and it is the thing to underwrite honestly before you deposit.

Access to your BTC for twelve months. No early exit, for any reason.

Immediate redemption. Collateral comes back 7–15 days after you repay.

The fall down to the put strike. Protection bounds your loss; it does not eliminate it.

When this is a good fit

  • You intend to hold BTC through the next twelve months anyway

  • You expect Bitcoin to appreciate moderately, trade sideways, or fall

  • You have a use for the USDC that justifies committing the collateral

  • You can repay from a source other than selling the redeemed BTC

  • You value a bounded outcome more than an uncapped one

When it is not

  • You expect Bitcoin to run far past the call strike within the term

  • You may need the BTC, or the money, before maturity

  • You would have to sell the redeemed collateral to repay

  • You are borrowing to buy more BTC that concentrates exposure rather than diversifying it

  • You are not comfortable with collateral held off-chain under a collar during the term

Compared with the alternatives

Route
What you give up

Sell your BTC

The position and all future upside, plus a taxable disposal today

DeFi lending platform

Interest that compounds, plus liquidation risk in a sharp fall

Do nothing

The use of capital your Bitcoin could have unlocked

BIMA Monthly Vault

Upside above the call strike, and access to your BTC for twelve months

Only one of those has a cost of zero in most outcomes and a bounded downside in all of them. And only one caps your upside. Both are true at once.
