Heads You Win. Tails... You Also Win.

The bull market case for holding sBTCD instead of farming stables.

We built BTCD and sBTCD knowing the primary use case would be collateral. sBTCD is the base layer for our USD Vault and BTC Vault, which loop it into pure-USD and pure-BTC yield, and those products are performing great. If you need dollar yield or Bitcoin yield with zero exposure drift, the vaults are the answer.

We also get the stablecoin pocket. Everyone runs one. Rotating between yield-bearing dollars, lending markets, and whatever the points meta is paying this month is a legitimate strategy.

But sometimes you need to take a step back and think about what you're doing, and why you spend 12 hours a day on this god forsaken app. Presumably the answer is to end the cycle with more money than you started with, without taking risks that vaporize the principal. Which raises an uncomfortable question about farming stables through a Bitcoin bull market.

Watch the simulation: One simulated year compares BTC, sBTCD and a stablecoin farm under stated yield assumptions; the animation is illustrative, not a forecast.

The quiet part

Internally we spend a lot of time talking about sBTCD as a core portfolio asset, particularly in bull markets. We've been hush about encouraging anyone to hold it directly. A market like this is exactly the use case.

What sBTCD actually is

BTCD is pegged to a continuous 50/50 BTC/USD exposure. The peg tracks the square root of the BTC price, so it carries half of Bitcoin's exposure at any moment. Stake it and you hold sBTCD, a claim on the backing portfolio's excess yield that autocompounds. One sBTCD represents a growing amount of BTCD over time.

Under the hood, the portfolio is doing what you do manually, plus a few things you can't. It holds the same class of yield-bearing dollar assets you're rotating between, assuming you know how to analyze risk and diversify your exposure. It holds yield-bearing Bitcoin. And it runs a rebalancing engine around the 50/50 target that sells Bitcoin strength and buys Bitcoin weakness, every day, forever. That harvest is structurally long volatility. It gets paid by the market moving, which is the one thing a bull market never fails to produce.

Every asset in the portfolio earns yield, but only stakers get paid. Yield generated on unstaked BTCD flows to the staking contract, which is why sBTCD's backtested returns (~8–14% APY across four years of hourly data, depending on where DeFi rates sit) can run above what the underlying assets earn on their own.

The bull market math

If Bitcoin doubles, the BTCD peg rises ~41% before a single dollar of yield. You didn't catch all of it. You also weren't sitting in full stables feeling the fomo. And when the inevitable air pocket hits — even great bull markets serve up 30% drawdowns — the peg gives back ~16%, not 30.

Compare that to the farm. A stablecoin position's best case is its APY. sBTCD inverts the shape: open-ended participation in Bitcoin's upside at half exposure, dampened drawdowns, and a yield engine that gets stronger when volatility shows up.

And the work. No weekly rotations. No claim-and-compound chores. One token. Hold it.

The whole cycle

The real magic isn't in any single move. It's the compounding of yield across the cycle. Yield stacking on top of half-exposure Bitcoin through every leg up and every drawdown has the potential to leave you in a better place than simply holding BTC or farming stables. Bitcoin rips? You're up, plus yield. Bitcoin chops sideways for six months? The volatility harvest and the asset yield keep compounding anyway. There is even a scenario in which this rally is a head fake and Bitcoin falls but the yield you earned by holding sBTCD offsets the losses. Heads you win. Tails... you also win.

To be clear about the risks: sBTCD is not a stablecoin. It carries roughly half of Bitcoin's directional exposure, so in a sustained bear its price leg drifts down while the yield offsets. The figures above are backtested targets, not promises. The portfolio is managed with custodied assets — security reviewed by Nethermind and Omniscia, with on-chain backing you can verify — under trust assumptions similar to the largest synthetic-dollar protocols.

But if you're going to spend 12 hours a day on this app anyway, maybe spend them holding the thing that wins both coin flips.
