Platform-by-Platform Comparison
1. PolyGram — Best for International Users
PolyGram via polygram.ink grants straightforward access to Polymarket's underlying liquidity pools. Notable benefits include:
- Direct connection to Polymarket's complete order book without requiring cryptocurrency holdings
- Fiat deposit channels using standard payment cards — no USDC conversion needed upfront

Manifold operates primarily using virtual currency (mana), positioning itself as an educational sandbox for learning prediction market dynamics without capital at stake. A monetised version exists but operates under constraints.
