How to Use ME10001: Stablecoin Peg Metrics in Trading

Stablecoin peg data is foundational for every crypto trade. When USDT depegs, it ripples through BTC spot, perpetuals, MSTR stock, and Bitcoin ETFs simultaneously—but at different speeds and magnitudes. Understanding these dynamics creates alpha.

Why Madjik's ME10001 Data is Unique

Traditional data sources show you USDT price on one exchange. Madjik aggregates:

• 50+ liquidity sources (CEX, DEX, OTC desks)
• Real-time reserve composition (not quarterly attestations)
• Redemption velocity (early warning of runs)
• Cross-exchange spread matrices (arbitrage opportunities)

This 360° view lets you act before others see the signal.

Strategy 1: Cross-Asset Depeg Arbitrage (No Leverage)

The Opportunity: When USDT trades at $0.995, BTC/USDT shows ~0.5% higher BTC price than BTC/USD. This creates simultaneous arbitrage across spot, ETFs, and MSTR.
