This Is the "Polymarket" for Bitcoin Miners

<p>Matteo Spinosa, founder and CEO of Doefin, built the first accessible prediction market for Bitcoin miners to hedge difficulty. Doefin lets miners and traders take a directional view on network hashrate — or lock in revenue certainty before difficulty spikes — using a Polymarket-style venue where price equals probability.</p><p><br></p><p>In this episode, Matteo breaks down why Bitcoin miners have historically been unbankable and uninvestable: difficulty volatility has run twice as volatile as the S&amp;P 500, making cash flow impossible to forecast. Doefin gives miners a primitive tool to stabilize revenue, or to speculate on where hashrate is going.</p><p><br></p><p>We cover how the Oracle works (SHA-256 validation of Bitcoin block headers, secured by the network itself), why settlement is non-custodial via cbBTC on Base, and how a miner can hedge a specific amount of petahash against a difficulty increase. Matteo also walks through a live demo of the platform, explains the &quot;For Miners&quot; hedging tool, and shares why Doefin stays out of scope regulation-wise with legal opinions in the UK and Mauritius.</p><p><br></p><p>Doefin launched to the public one week before recording, already has seven miners trading (roughly 0.15 BTC in volume), and is building toward a full forward curve for hashrate.</p><p><br></p><p>Guest: Matteo Spinosa, CEO and Founder of Doefin</p><p><br></p><p>Doefin: https://www.doefin.com/</p><p>Matteo on X: https://x.com/MatteoDoefin</p><p>Doefin on X: https://x.com/DoefinOfficial</p><p><br></p><p>Timestamps:</p><p><br></p><p>0:00 Intro: what is Doefin and the gap it fills</p><p>4:00 Price equals probability explained</p><p>9:30 The Oracle problem: how difficulty is validated</p><p>15:00 Liquidity and finding the first miners</p><p>20:30 Licensing, non-custodial structure and regulation</p><p>25:00 Platform demo: deposits, markets and taking a position</p><p>32:00 The &quot;For Miners&quot; hedging tool walkthrough</p><p>38:00 What&#39;s next: forward curve, Asia and scaling</p><p><br></p><p>Sponsored by:</p><p><br></p><p>Altair Technology.
