The crypto prop firm has granted over $50M in prop trading capital to 3,500+ traders across 150+ countries.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<a href="https://www.sizeprop.com/" rel="noopener noreferrer nofollow">SizeProp</a>, the crypto-native proprietary trading firm, today announced the close of its pre-seed funding round led by <a href="https://www.igloo.inc/" rel="noopener noreferrer nofollow">Igloo Inc.</a>, the company behind Pudgy Penguins. The round was structured as a SAFE.
<blockquote>Windra Thio, Founder of SizeProp: "Igloo's backing isn't just capital, it's validation that prop trading is a real, fast-moving category. We don't see other firms as competitors; every firm growing this space gives more talented traders a real shot. The bigger it gets, the better for everyone."

 <li>Onboarded thousands of new users into prop trading, generating over $3B of trading volume</li>

 <li>Launched the first incentivized rewards program in crypto prop trading</li>
</ul>
A New Wave in Crypto Trading
Crypto prop trading is emerging as one of the fastest-growing categories in the industry, driven by the explosion of perpetual swap volumes, a generation of skilled traders who don't want to deposit their own capital, and a category historically dominated by whitelabeled forex tooling that was never built for crypto.
What's next&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
SizeProp is focused on a few things over the next 12 months:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<ul>
 <li>Onboarding non-crypto-native traders. Making the platform approachable for traders coming from forex, equities, and traditional prop firms, not just crypto natives&nbsp;</li>
 <li>Reaching developing regions. Doubling down on markets where prop trading is changing lives the most, including India, Nigeria, Turkey, Brazil, and Southeast Asia.</li>
 <li>Building closer ties with the broader Igloo network.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</li>
 <li>Growing the team across marketing, operations, and risk management&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</li>
</ul>
