Reality of 'Flash Boys' and HFT effects

In this episode, we examine what actually happens when crypto markets break — how leverage builds beneath the surface, liquidity disappears, and liquidation cascades turn volatility into systemic failure.

Doug Colkitt, a quantitative trader and DeFi builder whose experience spans both traditional finance and crypto market structure. Doug began his career on Wall Street at Citigroup before moving into high-frequency trading at Citadel during the 2008 financial crisis. He later built and traded his own systems across futures, volatility products, and international equities, including running a major market-making operation in Turkish stocks.

Today, Doug focuses on crypto and DeFi infrastructure, working with perpetual futures, liquidation mechanics, and exchange design. We discuss why traders still get wiped out when they think they’re hedged, how liquidation cascades accelerate, and what recent market failures reveal about leverage and market structure under stress.
